Very powerful... Really like it so far

Very powerful. Works great in most occasions. The only problem I found is that when I used it for my hummus, it wants to take off to very high rpms and I have to give it little pulses at the lowest level.

Good stuff. Been using it for over a year and no big issues.

but have not yet used it too much....I think if box glass would be better? If it is broken, what can do?

Very similar to the Vitamix, but for a fraction of the price. Not as sturdy as the Vitamix, but that is what I would expect for a less costly machine. So far I have only made a few smoothies with it, but they have been great: really well blended in a short time. Glad the machine came with a tamper as it was needed for the frozen fruit.

So far, so good..quite loud!!
