Better than any others.
Yes, it is the small d ring that is the problem like others have stated.  Yes, the strap gets a bit twisted.  But here, in my 7th week after a humour us fracture I can safely say THANK YOU to the company Core flex for this excellent alternative to the hot, sweaty, slipping and awful slings available.  I replaced the d ring with a medium carabiner and it works excellent and hope up my arm with heavy pressure.  I have now tried 6 slings from the hospital and Amazon and this is the only one that has held up.<br /><br />Do not listen to anyone who turns you away, this cuff and strap is well worth it.
