This is the one!
Color: Gray
I ended up going with another brand, which I returned because it was impossible to insert the batteries into the too-tight compartment (other reviewers had the same issue and I should have listened). So I bought this one and not only is the battery compartment ample size and easy to insert the batteries into, the company even sends you two AA batteries to start you off! I also very much appreciate the fact that you don't have to hold down the button, just push it once to start and push it again to stop. It's powerful and I love that it sits in its own stand and looks nice in my kitchen while doing so.

Good idea great product
Color: Gloss Black
I bought this as a gift. The person loves it. It’s very compact. She puts it in her bag and travels with it. It’s easy because you can charge it at home and then it’s already. She sometimes brings her charger with her so she can use it out.

Works great.
Color: Gloss Black
We preferred this model because the button is on top of the unit, making it easier to use. And we do use it often. The battery lasts for a reasonable amount of time too, and charges quickly on USB.

Great Product - Stop Wasting Batteries!
Color: Gloss Black
Super happy with this purchase and so glad it's rechargeable. So much better than the fancy brand we had that went through batteries like crazy and had a wobbly shaft. Lots of power and can be easily used for travel as we do for blending protein powder and cream into coffee. It's already traveled to Europe twice, Tahiti, Australia and a Panama cruise and still working like the day we got it. We're very pleased with the quality and the price.
