I love them, they make it so much easier to progressive overload with dumbbells and weight stacks. I highly recommend.

I've added a number of sets of these, and they've been a great investment for incrementally loading my dumbbells. Over time it will save me some money for the home gym.

I hesitated to buy these at first because of the high price point, but I could not be happier with the product and the value. Absolutely worth the price. “Feels” like a very high quality product, too.
I use them with a Powerblock Pro set and they work so perfectly it’s like they’re made for it specifically. Allows you to get those 12.5 lb / 22.5 / 32.5 / etc increments that the set can’t do. Simple to add / remove. So quick that it doesn’t disrupt the workout at all. Just the right amount of magnetism that they’re easy to remove, but you don’t worry about them falling off, either.
And they work great with the Powerblock straight bar if you have that, too. Just add them right to the flat part of the handles where the weight chart is displayed. And again, this allows you to fill the holes of 45 lb / 65 / 85 that the bar can’t do on its own.
Perfection!

Sticks on great to both dumbbells and barbell plates but also use for cable pully stacks (I use with the coated Powerblocks and sticks strongly to them without falling off). Fantastic way to add microweights to devices and or quick adjustments between exercises without rests. Only wish the hole would fit Olympic bars – but sticks on the Olympic plates without issue. Essential part of my home gym and would buy agains.
