It's okay... It just works. It does have this weird plastic burning smell from the external parts though but so far this hasn't affected the taste of the food/drink. I've only used it a few times but it functions. 
**Update after using multiple times: I guess you get what you pay for. It's poor quality in terms of the actual blending because it takes so much time to blend the softest of foods and because it takes such a long time with a lot of taking out, shaking, and then placing back on the blender, the drink comes out warm (along with the plastic burning smell).
