These little racks do exactly what I was hoping they would.  They're very sturdy and can really hold up the weight of the cans.  I love that the cans roll forward and you can see what you have instead of stacking them up.  The only little problem I've had with them is that I have that wire shelving and the racks seem to fall through the gaps, but I'm working on a remedy for that.  I love being organized!
