I liked my old one better because it had two speeds and it seemed better quality

Did not mix like I was expecting. Also, attempted the egg beater attachment to make scrambled eggs and had a big mess to clean up. I guess I was expecting more automation and better results in food preparation. This is not what I wanted. I would not purchase or recommend one.

There is a lock button so make sure you press that along with the power button! The blender attachment works well. I've tried using it directly in a sauce pan and that made a bit of a mess so I use the cup it came with but transferring soups/sauces can be cumbersome. I will have to say the whisk attachment makes a gigantic mess and I can't imagine a scenario where using it would be more efficient than whisking by hand. I've had this for 6 months and so far it seems to be working as well as it did in January.

Very flimsy overall. Assembly for whisk in pieces. And unable to get it to secure to the hand piece.

This is my second of these blenders. The company has tweaked the design so that you have to hold two buttons at once for it to run. The first iteration of the blender did not require this. I am not thrilled with the change but I do like the blender
