The handles are pretty much just plastered on to two 14" threaded bars. The plastic is very soft, for workout gear, and will compress when tightened. My experience was; I bought them, used them about for 10 or so tightening's, then the plastic stop that touches the weight on the grip began to tear badly!!! So I brought them back. They are useless, unless you buy a washer to put in between the plastic and your weight. Do not buy the apex dumbbell handles until they come out with the next gen.
Was this a gift?:
Bottom Line No, I would not recommend this to a friend
