Review on DOUBLE WHISK Milk Boss Frother by Gerardo Cibrian

First day with this whisk and I have to say it seems to pack a lot more punch than the previous two similar products from another brand. I'm not sure if the motor is better than my previous ones, or if the main benefit is the double crown head. My only complaint, however, is that the battery compartment has VERY tight tolerances. I tried three different types of AA batteries before finding a set that fits and allows the battery compartment to be locked in place. Finally regular Duracell disposable batteries came out but none of my variety of rechargeable batteries fit and didn't let the battery compartment lock, they were all too big. I would like to use rechargeable batteries in these devices as I use them several times a day and change the batteries every couple of weeks.
