Great for lifting (obvi) and keeps the plates in check. They hold plates very securely. They are heavier duty, plastic used is thicker, the design with the screws and shape seem to really help it hold the bar better as well.

Finally invested in these. Things break, it happens but they handled the situation with respect and i value that as a customer.

These collars are fantastic. Im glad i didn't spend a ton of money on "the good ones" these work well.

Bought it on september 12, and broke (dismantled) in a month of use. There is nothing holding that pin in place, and as the lever moves against it it pushes it out. Manufacturer failed to assemble correctly.
