Like many people, I got this as a replacement for a dead Keurig. I looked at a lot of machines out there, and I was specifically looking for something that could brew K-cups, coffee grounds or coffee soft pods. Most of the machines that could do this were expensive ($100+). This product though, it's only half that, and it can do the same thing, and it does the same thing very well.
One nice thing about the Keurig was that it was very fast, as it pushed the hot water through with a good amount of pressure. This resulted in a quick brew, no doubt, but when using my own coffee grounds, it was not very easy to find the perfect sweet spot that made GOOD coffee. K-cups, they were usually perfect.
This unit, however, is the slightly slower 'drip' method, and instead of ~1.0 min for a cup from one of the Keurig model, this one takes ~2.0 mins for a cup. However, because the water has contact with the coffee for substantially longer, the coffee made with my own grounds is absolutely better with this machine than the Keurig. The K-cups are just as good, no better or worse than a Keurig machine (which is a good thing).
So, what it boils down to is that the coffee takes maybe a minute longer to brew, but it does so with the drip technique rather than the forced-water technique. This results in the same taste for K-cups, but BETTER taste when brewing your own coffee. And unlike the Keurig, you don't have to buy a separate piece of equipment to use your own coffee grounds. Also, you get the added bonus (over the Keurig) of being able to buy/use coffee soft pods, which is awesome. Much like the K-cup world, there are a lot of coffee soft pod makers out there with some fantastic coffees in ready-to-go little pods.
End result, I'm actually extremely satisfied and a little surprised by this great little machine. I don't have any negative things to say about the Keurig, but honestly, this seems just as good, for less money, and more functionality.
