I got this device just few days back. It is a good copy of nutribullet but I am not really impressed with the performance. Just tried to make one recipe from the book which came with the Tower Vita Blend. When I used the cross blade it was leaking so I gave up the idea of using it and used the flat blade. Surprisingly it started losing power and I had to throw the contents of shake in the bin. Wasn't a really good experience for me. I got so disheartened that I packed it back and now it is lying in the store. Surprisingly it comes with a long warranty. After experiencing the product, I didn't even bothered to call the customer service.
