Reviews for Keurig brewing systems can be found at QVC and Amazon.com. As an easy-to-use brewing system, the Keuring coffee brewer has favorable reviews from users who are generally happy with the machine.
The reviews for most of the Keurig brewing system machines are positive both on Amazon.com and QVC. One Amazon reviewer claims that he is happy with the hot and tasty cup of coffee from his Keurig machine and how quickly it makes it. A QVC reviewer claims that the price on the Keurig K45 coffee maker is a good deal for everything that comes with it. Keurig makes both commercial and home-use machines, both of which have mostly positive reviews that are in the four- to five-star range.
There are two home-use models, the K450 2.0 brewer and the K350 brewing system, that only have two to three-star reviews on Amazon.com. A reviewer gave the K450 2.0 brewer one star because it only brews pods that are specially marked with a stamp. She says the company uses digital restriction malware on the machine to detect the stamp. A third Amazon.com reviewer claims that he has stopped using the Keurig K350 brewing system because when he tries to make coffee with other pod brands not approved by Keurig, it produces an error message.
