Find the straight profile of these uncomfortable, i used them when i was 130kg and found another curved set that was much nicer. Im a little smaller now so might give them another try
These are great for getting the most out of a single atlas stone. I tried cheaping out and using random styrofoam pieces which was more hassle than its worth. Get the really thing!
I hate using these, they are sharp and I always catch my fingers in them. Only use them on something that they stay on. Saying that, they work and do what their supposed to do
