I have a pair of "Haulin' Hooks". They weren't cheap, but they're well made, have been durable. I've had them for several years. Got them originally to help work around chronic tendonitis, which was irritated by gripping, especially during pulling exercises, so I used them every time I trained back for probably a year. Now I only use them when doing my heaviest deadlift sets if I need them, but they've held up very well.
