Rated 4 out of 5 by from Budget Collars First off, my experience with these so far have been good but take into account other reviews that mention the problems they have had with these because you very well could run into the same issues. These collars are paired with my Ohio Bar and fit like a glove, taking them on and off is a breeze. The lever on them feels sturdy but I can tell that they will EVENTUALLY (depending on amount of use) break because of the quality of materials not being anything too amazing or sturdy. I use them for 315 lb deadlifts and they keep the weights in place and only allow a little movement of the plates which I like. The inside of the collars have a nice thin rubber padding which keeps the barbell sleeves from being worn down as fast. These are definitely a great product for the price you are paying for them and will last you awhile..but not forever. These are definitely better than spring collars and velcro collars. Do be careful with dropping weights or anything heavy on these because that would likely cause these to break because of the materials.

Rated 2 out of 5 by from They move They move! I Purchased these with the intent to use them for my bench, squats, deadlifts and every time I use them on my dead lift the collars shift and I have to readjust the collars every set. I wish I would’ve spent the extra $10 and got the 50 to 5 $ set

Rated 2 out of 5 by from Worked for a year, now they are too loose. These worked great and were tight at first, now after a year they moved after every drop.

Rated 5 out of 5 by from Mighty Mights I bought these because the collars at my gym don't hold the plates tight after numerous drops. These have not dissappointed. They are easy to use and very light weight. The hold is great. Definititely a good buy for me.

Rated 4 out of 5 by from Reliable I bought these collars for my home gym, and I was not disappointed. I enjoy the look and feel of these collars compared to others. I haven't had any issues with these collars slipping or damaging my barbell. I would definitely recommend these for a budget home gym anytime.

Rated 5 out of 5 by from Great value (performance / $) Got these about a month ago -- my first pair of collars. Price is great, and I like the small form factor, too. Terrific performance during the CF Open -- no slipping or other problems. (Some reviewers said they are difficult to get on -- the key, as far as I can tell, is just ensuring the clip is completely open when moving on / off bar. You can unlock the clip, but it may not be completely open). Definitely recommend them.

Rated 5 out of 5 by from Great product Only thing to be cautious about is people complain about it being too tight. It’s like that for a reason... Just make sure clips totally up before sliding onto the bar and you will have no issues
