I own the 2.5 and the 5 lb versions...they are stupid expensive for what they are but they're magnetic and live on my lat pull machine it allows 2.5 lb jumps for tricep and shoulder work because the 10lb jumps are too much most times...if you commit to these you really need to get the 5 and the 2.5 if you want the ability to do all the steps within the 10lbs (2.5 ,5 and 7.5 ) they should be offered as a set....get on this PlateMate...once your gym has the essentials little things like these makes a big difference
