Query: Awkward shape, avoid it.

The shape conforms perfectly to the designer's hands, but unless you share the same DNA, I'd avoid this product. I've used many of these over the years and this is the only one I struggled with. Constantly shifting it to get it's high and low points in a place that was tolerable. I finally reversed it, pointing it towards me and it worked a little better. This just needs to be a simple pad. Instead, they've overdesigned it as a gimmick.
