Review on 4-Pack 1.5 Inch Swivel Stem Casters - 330 Lbs Capacity, Non-Marking Polyurethane Wheels & 3/8"- 16 X 1" Threaded Stems With Nuts For Furniture Carts Trolleys. by Robert Pierce

I bought these for my Bowflex dumbbells stand and they're perfect! I would highly recommend them to anyone that has the correct caster thread to receive them (check this before buying).

They are quiet, solid, and have a very smooth rolling action on my laminate wood floors.The only minor dislike (very minor) I have is that the lock release levers take more force to release than I would expect. If one is not careful they could get a pinched finger, but this is really minor in my opinion.
