These are definitely OSO knock offs and my pair is odd in that one holds noticeably tighter than the other. Also, it is sometimes hard to open them up enough to where they'll slide onto the olympic sleeves easily. I got tired of trying to make them work as dependable collars and have put them to other uses in my gym (e.g. see attached pic).

These D-handles are two of the oldest equipment in my gym and they've taken a lot of abuse over the years. They are still holding up great. My only complaint is that the knurling is a bit too passive. Also, some (though not I) might find the squeak of the rotating handles to be annoying, and even a deal breaker.

This sissy squat was part of an earlier iteration of my gym. It's marketed as performing the dual functions of the sissy squat and the hyperextension. With regard to the latter, I never felt safe doing hyperextensions on it. With regard to the former, the design of the foot roller impedes the performance of a good sissy squat. As one tightens the foot roller, it squeezes the top of one's feet, which feels uncomfortable during the actual sissy squat movement. I ultimately ended up upgrading to a more quality equipment made by Body-Solid.

Prior to these straps, I had the regular straps without the numbering, and they made changing the heights of my rings a chore. I did my best to eyeball their evenness, etc. These straps are numbered so they take the guesswork out of it, and make adjusting the height of the rings quick and easy. They are also pretty sturdy. I've had these for about two years and they are holding up great. There is hardly any signs of wear even though I use them several times weekly. For anyone seeking to include gymnastic rings in their gym, I'd recommend pairing them with these straps.

These wooden rings perform very well for their price point. I got the thicker version (1.25 inch) and they feel better in my hands during both pushing and pulling movements than the thinner (1 inch) rings I had before. These days, I use my rings for inverted rows and ring dips.

These bumper plates were part of a previous iteration of my gym. If I recall correctly, the 45 lb plates actually weighed 45 lbs. They were pretty dense so had a low bounce (though I only dropped them from knee height during deadlifts). Despite these positive features, I ultimately ended up selling them as a matter of principle when Vulcan Strength sued Gluck's Gym for giving his honest review of their allegedly shitty all-in-one rack.

This is a beefier version of Cap's regular hex bar that boasts a 32mm diameter grip, a loading sleeve length of 13 inches, and weighs a whopping 75 lbs empty. It lives up to the "mega" in its title. Its stated weight capacity is 1000 lbs and I can believe it seeing how robust it is. The knurling is a bit inconsistent, with the low handles being noticeably more aggressive than the high handles on my bar. Value-wise, people these days might opt for an open trap bar at a comparable price, but if you're looking for a basic "closed" trap bar that will get the job done and can take quite a bit of abuse, this is a good option.

Nothing fancy. Just old school cast iron plates that get the job done, but can be a hit or miss with regard to their stated weight. My 2.5 lb plates weigh 2.8 lbs each, for example.
