GREAT, until 2 blades broke off.

This was a great little blender until about 5 months into ownership two of the 4 blades broke off in my daughters smoothie. That's all we used it for - smoothies. Frozen fruit and milk. Didn't think that could break a blade but it did.
No, I would not recommend this to a friend.

My son gifted me with this lovely blender so I can make my protein shakes and salsa easily(and other things too,I'm sure). It is sleek and very easy to use. I LOVE the glass container as it is durable and oh so easy to clean! Thanks for the great product!
I would recommend this to a friend!

Makes perfect smoothies.

My smoothie machine died, so I bought this to replace it. And I like it much better. Unlike the smoothie maker, this has adjustable speed, and I can make a large amount at one time. I wish I had bought this in the first place. It feels very solid.
