I liked that this is portable, the cup is stainless steel, that it has a rechargeable battery and you don’t need to plug in to use. I also like that it came with a different lid to use for drinking as well as a straw and straw cleaner. It’s definitely convenient if you lack space or want to make smoothies on the go. It works pretty well. The biggest con for me is it is pretty loud.  Not a deal breaker for me, but might be for others. I do feel like I had to blend it a few times before it got to the consistency I wanted. This could be a me problem though, not the machine.
