Wahl Easy Pet Nail Clipper

I've been using these for about three weeks. At first glance I felt they looked a bit cumbersome and a bit too large (they have fat "legs" in order to fit the batteries for the grinder). They actually fit in to my hand okay (though my collegue found them too large and awkward for her hand). The first thing I did was to remove the guard which I felt obscured the view of the nail itself. That done, they were okay. However, the nail clipper itself doesn't seem sharp enough after about three weeks use. Finally, getting to the grinder bit - the head of the grinder tends to wobble and fall off easily - so the cap covering it needs to be removed in order to reseat it. The power in the grinder itself was better/more powerful than the Mikki battery operated grinder. And I really like the design overall, but unfortunately for me they just didn't really hold up they way I hoped.
