I have them! Got them for a birthday gift in May. I like them for some heavy lifting, but to tell you the truth, I don't use them a ton. I find them a little awkward for a few of the exercises, with the big bulky ends to them. So I end up using my 5's thru 15's dumbbells, and if I need more weight, than I will use them.
BTW..my husband ended up getting them for a pretty good price at Sears!
