Anyone one own these adjustable dumbbells? I'm interested in picking up a pair. They adjust from 5 to 90lbs. They also have an expansion kit that makes them go up to 125, which is good enough for what I'll use them for. Only issue I can see is the awkward shape. Comes with a lifetime warranty, obviously not meant to be dropped or thrown around. My old gym had a pair, I tried them out they're not so bad. But they're expensive. I have olympic adjustable dumbbells, main problem is not being able to lay them on quads to kick them up because they're not flat, and changing weights gets tedious. Also, putting 25lb plates on them make them really big and messes with the range of motion on certain lifts. Not to mention they're longer, too. I tend to just do more barbell work instead. I miss using dumbbells though. Thoughts?
