Question: I reads reviews that the K140 is noisy.  I have a Keurig Platinum plus at home.  Can anyone tell me how they compare?
Document: Love it. Super easy to use. Tons and tons of flavors and roasts. I would recommend this to anyone who is looking at a Keurig system.
I purchased this Keurig for our office and it is wonderful, it brews fast and allows quick selecting of cup size with the dial we are very happy with it. As a matter of fact one of the women in the office liked it so much she went to Amazon and bought the same one for her home.
I bought my Keurig B140 at a discount store about 8 years ago for $15.00, I don't think they knew what kind of a product they had, but let me tell you, after 8 years this thing is the BEST coffee maker I have ever owned. I will definitely purchase another one!! The only drawback that I have is the cleaning cycle.
Purchased two of the B140 Commercial Brewers from W.B.Mason as Christmas presents for $65 a piece. Quality far exceeds the home brewer and the unit includes a water storage tank. The only drawback is the M K-Cup reuseable coffee filters do not fit the unit, even though when I telephoned Keurig the CSR informed me that they did. I ordered two kits and xtra filters at a cost of $60. (working on return and refund of shipping charges, now).
When my Keurig died I did some online investigation and read about the Mr. Coffee version. Since the reviews were mixed, I chose a refurbished one listed on Amazon and I absolutely love it. True, it isn't as fancy as the Keurig with whistles and bells, but it brews one heck of a cup of coffee. In fact, the coffee seems stronger than the Keurig brewed. The water temperature is consistently hot without having to fiddle with various settings.
This is the one to get for your home if you're looking for a trouble free unit.Get one before they discontinue the line. Keurig is going the direction of selling commercial units direct through distributors so this type of unit may not be continued. You probably won't be able to buy one on Amazon, but Staples and Quill were selling them.
The vibration this machine makes when filling the inner tank shakes the walls! I have a Cuisinart at home and my daughter has the regular home version of this model...the noise is no where near as bad. It should have been returned asap.
I've owned a couple of different Keurigs and by far, this is the best model. I use it in my bar as I needed something commercially rated, but I didn't want a typical Bunn brewer where a lot gets thrown away. We don't sell a lot of coffee, but my employees and myself do drink enough. The quality of construction is more rugged than home models (as you would expect) and it brews perfectly.
Bought this because I was tired of my companies terrible coffee. I work in IT, so I need sealed travel mugs so as not to be the guy who spills his coffee on everything, so I bought this unit because the personal units do not fit my mugs and the price was right. It works as well as my home unit and has a number of commercial cleaning/rinsing features I had not seen on home units.Only complaint I have is the noise.
Heats much faster than the home unit and much easier to drain for cleaning purposes.
Answer: Yes, they have improved the sound on the home brewers. The commercial brewers are designed for an office and meet commercial fire code requirements in my area. The noise isn't noticeable in an open office and the benefits outweigh the negs. The machine is designed to be always ready to brew one cup after another and there is a cleaning system built in so that you can easily drain the unit from time to time. Hope my response has helped you.
