Does anyone use one of these ?

I've been using a Natural keyboard for as long as I can remember and I love it. But my rather large-ish bt mouse died a few months ago and I've made do with a little mobile mouse 1000 I picked up for my kids when they were smaller but it's not doing my wrist any favours. I'm also now at a desk with an adjustable keyboard mount and I don't have all that much space and this looks smaller because the number pad is separate.

I'm just wondering if people find them to be any good.

Thanks
