COLLIERS XM OLYMPIC 50 MM À VERROUILLAGE MAGNÉTIQUE

This was our first time making this type of purchase. The quality of all of our items (Olympic bar, bumper weights, bench) were all great products. Everything came without any problems and we are enjoying it.

Picked these up and overall I am pleased. Purchased them for the magnetic feature. The magnets are not overly strong but really JUST enough to hold it to the rack without sliding down.
I did expect them to hold a bit stronger but this hasn't caused any issues. Haven't noticed any unanticipated drawback to having the magnets magnets yet either. Unlatching was pretty stiff initially (the little locking piece took a decent amount of force to push) but they seemed to have loosened up with use over the past couple of weeks.

Have been using for 2 weeks, and the quality is superb. The value is definitely there.

The magnets are quite weak so you need to be careful to how you are placing them in your rack upright over wise it will slip gently and fall. Even if the are overall good collars, I recommande you buying a more classic model and ad by yourself magnets from HomeDepot.
