Got these about 4 years ago.
At the time, the Peppins were out of my price range.
I have used them quite a bit, and I do not throw them around. I never drop them, or throw them on the floor, and am always sure to be as gentle as possible when setting them down.
Some coating has come off the plates, but overall the black coating has held up well.
Handles have no sign of wear.
I have had two minor issues with them however.
One of the 2.5 lb weight inserts on the inside seems to get "stuck" and does not slide out as well as it should. The insert itself has minimal wear and does not get stuck because of rust build up or anything like that. I can get it out, but usually have to shake/bang the handle on a horse stall mat of course, to get it out. Not a huge deal, but should not happen and hinders the convenience of adjustable dumbbells.
Second issue is, on one dumbbell, when I select 60lbs, sometimes the 70lb plate will be stuck to it on the outside. Again, not sure why this happens but for the price it is not something I should have to deal with.
Overall, this is a good product and I am sure these issues would not happen with 98% of other units as long as you care for them like I have.
I would recommend to a friend, but it probably would not be my first recommendation for an adjustable dumbbell.
