Keurig K155 Review

Thanks in part to the commitment of the manufacturers to increase the convenience and speed of the coffee-making process, Keurig coffee makers have always been praised for their amazing attention to detail and efficient design. This is exemplified by how customers have been quick to praise the ever-shortening brew times of the coffee makers.

However, this speed and convenience usually come with their well-publicized flaws. For one, critics of the Keurig line of coffee makers and their K-cups have always pointed to the weak flavor and strength of the coffee made. It has been claimed that the lower brewing temperatures and lack of sufficient contact between the coffee beans and water are to blame for this.

Another source of debate has been whether the K-cups and K-pods that are used with the machine are safe to use because of the use of plastic in their manufacture. But it should be noted that different customers have different preferences, and what may be considered weak to others might not be to you. Also, unsubstantiated criticisms aside, the Keurig coffee machines have always delivered on their promise of speed and convenience, and the Keurig K155 is no different.

Overall performance and functions

Keurig K155 Review

The K155 goes some ways to defeating arguments supporting the weakness of coffee made with Keurigs. This particular Keurig coffee maker accepts third-party K-cups, thus significantly increasing the number of coffee flavors available to coffee drinkers using it. It then combines this widening range of potential flavors with a better heating system. You get to brew third party coffee, which is usually cheaper) and you also get to make your coffee using a newer, more efficient technology.

The improvement in the quality of service this machine supplies over earlier models of coffee machines from the same manufacturer is most exemplified by the reviews the appliance has garnered from customers. These reviews could be accessed online and should further convince you of its suitability for your coffee-making needs.

It also helps the popularity of the K155 dues to its brewing capacity and rapid brewing times; the machine is suitable for use in workplaces and office settings where there may be many mouths to satisfy. This is why the appliance is included among the commercial brewer systems series of the manufacturer’s products.

Material

Despite the Keurig k155 being made mostly of plastic, it is a very strong machine. Besides, the plastic exterior is still very pleasing to look at. In line with the aesthetic quality expected of Keurig coffee makers, the k155 is sleek and would easily fit in at your workplace or home.

Thanks to the mostly plastic body, the appliance is not very heavy; if anything, it should be considered light relative to other coffee makers of similar capacities. The machine is not all plastic, though; the mug or cup platform possesses chrome-plated accents, which combine perfectly with the general look of the appliance to give it a high-tech appearance.

On the interior, where the most real magic occurs, the machine still uses a lot of plastic, but this is heat-resistant and still safe. Though, as pointed out earlier, the effects of this plastic on the safety of the coffee being made has been a source of debate.

Capacity

Thanks to the UL commercial certification possessed by the Keurig K155, the machine is suitable for use in offices and workplaces. This doesn’t make it any less right for homes, especially large ones where its capacity would be most welcomed. This certification implies that the machine is considered capable of dealing with high demand and constant brewing.

When this capability is combined with a brewing capacity that guarantees about 18 cups in one go, you understand just why this coffee machine might feel wasted in smaller settings. This doesn’t mean the machine is suitable to take on the job of satisfying hundreds of mouths, and you should probably watch the frequency with which the appliance is used as this could affect its life span.

Interface

The interface is easily one of the biggest advantages the K155 has over competitors in the market. The coffee maker uses an intuitive LCD touch screen system to create an easy-to-use coffee machine. Other than this screen (which manages all of the main controls to be accessed), the only other control on the entire machine is the power switch.

Once the machine is turned on, all settings that go into making your coffee, such as brew temperature, brew size, or water level, can be taken care of from the screen. In cases where the screen reads an error like the popular “Prime error,” simple troubleshooting procedures should do the trick. Troubleshooting tips in the order they are most likely to be needed are available online to help.

The trilingual nature of the LCD also ensures that the machine can be used effectively by users of English, French, and Spanish.

Reservoir design

The reservoir uses a pour-over design which is difficult to believe when coupled with the average time taken to brew a cup, but that’s what the manufacturers say, and there’s no reason not to believe them; their reputation is that solid.

Other than that, the reservoir has a 90 oz. capacity and is designed to be removable. This means that it can be dislodged when it needs to be cleaned, descaled, or filled up and replaced when that is done. Dislodging the tank might be tough, but once you get the technique right, it comes quite naturally.

One flaw to the design of the Keurig reservoir might be the need for the Keurig brand cleanser, particularly when trying to descale; however, this should not be much of a problem.

Keurig K155 Review

Brew sizes

The brew size refers to the cup sizes the machine is brewing for. Despite the being capacity of the machine, the brew size would affect the actual number of cups that you could get every time the appliance is run.

The Keurig K155 offers four brew sizes, one less than some of its predecessors. These brew sizes could be preset to ensure that only one is available. This would mean that users of the machine on that setting would be able to determine just when a water refill might be necessary by simply monitoring the number of cups that have been made.

The sizes selected could also impact the overall strength of the coffee that would be made. This setting can easily be made through the LCD touch screen at the front of the machine.

Brew time

The biggest advantage of the Keurig coffee makers has always been their ability to deliver a quality cup of coffee in super-quick time. This hasn’t changed with the K155. The machine is being advertised as being capable of brewing coffee in less than a minute Trusted Source Brew temperature, at fixed brew strength and extraction, has little impact on the sensory profile of drip brew coffee | Scientific Reports The brew temperature is widely considered a key parameter affecting the final quality of coffee, with a temperature near 93 °C often described as optimal. In particular, drip brewers that do not achieve a minimum brew temperature of 92 °C within a prescribed time period fail their certification. There is little empirical evidence in terms of rigorous sensory descriptive analysis or consumer preference testing, however, to support any particular range of brew temperatures. www.nature.com , and this is just about accurate.

The speed and capacity are one of the reasons the Keurig K155 is popular in workplaces, as you can brew for multiple cups very fast.

Durability and warranty

Though the Keurig K155 is quite stylish, it doesn’t achieve this to the detriment of durability. The machine is made from high-quality parts (such as the heat-resistant plastic material) to ensure this durability, but good maintenance practice would go a long way in extending the life span.

Maintenance here would include cleaning. The sleek and streamlined design of the k155 provides a few nooks and crannies for dirt and dust to accumulate. This, and the plastic exterior, makes it easy to clean. The chrome-accented mug platform is also easy to clean, but unlike the plastic parts, it is a drone to coffee and hard water stains. Improving the quality of your water and avoiding spillage could help with the latter, but the former might prove hard to prevent in the long run.

The water tank or reservoir of the machine can be dislodged and removed for cleaning and descaling. This is important to remove the plastic taste that many have complained of after using the Keurig K155. Also, neglecting the need for descaling comes with its problems. Mineral build-up in the reservoir could block water from flowing freely; minimize the effect of the heating element, and affect the taste of your coffee. To prevent this problem, you could invest in filters that improve the quality of your water. Such filters would also reduce the amount of effort that goes into descaling and the frequency with which you would need to descale.

The Keurig K155 water reservoir could be removed, and the machine could be connected directly to your water supply. However, I would advise that you leave any plans for such a connection until the warranty period is over, as it would void your warranty.

There is a warranty policy available on every purchase of this coffee maker. The manufacturers also offer customer support if a user needs to troubleshoot the machine or repair it. Further information on the warranty could be obtained by accessing the company website or contacting the customer support team.

Price tag

Some might be quick to label the K155 as expensive, but that would be a hasty conclusion on their part. In my opinion, the capacity and speed offered by the Keurig k155 are justified at this price. The machine is also versatile enough to be used at home or in a moderately sized workplace.  This suitability for use in a commercial setting is not just based on word of mouth alone, though the appliance is certified.  Its certification indicates that it has the capability and durability to meet commercial demands.

Even though this review has not emphasized the fact, the Keurig K155 can also make tea and other beverages, showing flexibility in function. A combination of all these supports the pricing of this coffee machine and depending on which retailer the K155 is purchased from, and you may even be able to get a cheaper deal. Either way, the machine would offer you a very high value for money spent if used within its capabilities.

Key features

Though the general function of coffee makers is the same, they tend to contain additional features for extra convenience. These features vary from manufacturer to manufacturer and from brand to brand. The features possessed by the Keurig K155 are:

  • A store and drain function to help remove water from the reservoir before transport
  • A pour-over, removable water reservoir with a max capacity of about 90 oz.
  • An intuitive touch screen interface to ease the use of the coffee maker
  • Four brew sizes to use from
  • Brewing system that allows the use of third-party coffee pods

This combination of features is important to the overall quality Trusted Source How to Brew Coffee Prepared coffee begins to lose its optimal taste moments after brewing, so only make as much coffee as you’ll drink. Otherwise, coffee can be poured into a warmed, insulated thermos to be consumed within an hour. www.ncausa.org and convenience of the appliance, but no product is completely perfect. The Keurig K155 has its advantages and disadvantages, and these are listed in the table below.

Conclusion

As I’ve tried to explain in this Keurig K155 review, the reputation of the manufacturers ensures that there are very few doubts as to the quality of service of this appliance despite some of the concerns that are publicly shared.

However, if extra confirmation is needed, you could always check out the customer reviews that are readily available online for more assurance; the word of others enjoying the service of this machine should assuage any fears that you may feel.

Once done with your research, be sure to purchase this coffee maker to join the league of people enjoying a quick, convenient coffee-making service.
