Query: Kind of bulky and uncomfortable.

This just didn't do it for me. I found it really bulky. If you're using it in pullout keyboard drawer, it may not fit right. I didn't find it all that comfortable either. The gel pad wasn't cushy enough for me. I like one with more give to it. They might as well have used hard plastic.And for the money, I definitely don't endorse this product.Usually I'm really happy with 3M products, this one just seems like a waste of materials.
