I bought this unit today so I could make protein shakes for myself. I used it as soon as I got home the only issue I had was trying to get it in the locked position so it would start. My hands are not large enough or strong enough to do this but I was lucky to have someone here that was able to do it for me.
My husband recently purchased this personal blender for me after my Magic Bullet stopped working. We make our own Iced Cappuccinos every day (sometimes several times a day) and we love it!! It actually makes a better ice blend than our old machine. Our only wish is that it would come with an additional smaller-sized cup for those days when a gigantic coffee is too much lol :)
