I bought this to make my own version of the Dunkin Donuts Coffee Coolata. There is a rubber ring that seals the top that continually comes off and wraps itself around the blades. I won't be surprised if it gets shredded one of these days. Other than that, I like the machine. Definately for 1 person. Serves my needs perfectly. Easy to clean and simple to use. Dunkin Donuts stopped getting my money the day after it arrived.

I HAVE USED THIS FOR PROTEIN SHAKES, IT'S VERY GOOD INMIXING INGREDIANTS AND CHOPPIING ICE, I AM PLEASED WITH THE PRODUCT. THE MIXING CONTAINER THAT SERVES AS A TO GO CUP, IS A PLUS AND IT CLEANS EASILY. i REALLY LIKE IT. lYNNE

All I can say is this is the perfect personal blender. I have limited counter space and this is the perfect size. Glad I found it. As far a durability, I gave it 3 stars because I haven't had it long enough, but it seems to be good. Just what I needed. Thank you.
