PlateMate 2-Pcs Magnetic Donut 1.25-Lb Workout Microload Weight Plate Add-Ons (2.5 lb. Set)

These things are great for if you need a smaller weight increase than 5 pounds. They are perfect for PowerBlocks when you need smaller than a 5 pound increase (e.g. some of the configurations allow 2.5 pound weight increases, while others only allow 5 pound weight increases 5, 7.5, 10, 15, 17.5, 20, 25, 27.5, 30, 35, etc.)

It has ONE JOB- Stay on the dumbbell. It never fails to fail. Horrible product. Complete rip off

They're great for what I need them to do, which is to use them as change plates on the ends of my Powerblock Dumbbells. Ther magnets are strong enough for then to attach well to those. However, they do NOT fit on my standard Olympic barbells which is what they are supposed to work with. The hole is too small for the Olympic barbell.

Great workout material. Was a gift for a young man just starting out. Especially a real asset for someone with hardly any equipment.

Love these weights for giving variability to my current weight set. Allows us to increase in smaller increments when and keep form rather than jumping up 5lbs which can be 10-30% increase for my wife’s weights. Only dislike is they are not sized to fit on olympic bars, the holes are two small.

A bit pricey, but then again, if one bought a pair of regular circle magnets of the same weight, the cost is the same.

Product works perfect for what we need.

instant 2.5 pound bump for my metal dumbbells so I don't have to buy all the increments. I use these first and then use the clamp on version when I want to increase by 5. The magnets are very powerful ... great product.
