I researched blenders like crazy and found that this was one of the best and had everything I wanted. It is powerful. I use it mostly for vegetable smoothies in the morning and it is great. blends perfectly. I love the cup sizes (I mostly make for 1-2 people) but they are too small to make cocktails for a bunch of people when I have guests over so I make a couple batches.
Overall, it works great and is exactly what I was looking for. I haven't had problems with it yet and have not even noticed it is refurbished (I've had it over 6 months now). Great buy!
