Once a month I need to flip the thing and plug it in. The amount of hassle is almost zero. It charges quickly enough that on a few minutes of charging it can limp along for another hour or so.

I've had other cordless mice that needed to be charged in a special cradle, which is basically the same thing, and I never heard anyone bitching about "hilariously backwards" design. Most people reviewing the product thought that was convenient.
