Got this one second hand so can't speak to price but it did an ok job inverting a light weight. It was easy to adjust and use, but with the lighter weight limit it would only be useful to a small portion of the strength community. Though it folds to take up less space,.it didn't make the cut when gym space became more limited.

Awesome modified yoke used by a promoter in North Dakota contest I competed in. It was empty for the lighter classes, then weight was added in the form of a bale at a time each side. This type of setup may also work for adding motorcycles or other items to make unique themed carries. The octoberfest themed contest had this and a pumpkin basket deadlift.

None currently in the gym but I've found my new local source. Unfortunately I am limited on space and the biggest downside of tires is how much space they take up, especially when you are trying to find the right weight. Upside is they are free.

Use this one at the gym when I have no other options. It does it's basic job. If it's the only one available I throw on straps for deadlifts since it has almost no grip.

I used these as a tool for "dorm room" training on several work trips when I didn't have time or transportation to easily make it to a gym. Now I still use some of the bands for stretching and warming up. Biggest issue is if someone isn't paying attention to how they have the bands set it they could rub on sharp edges causing damage.

Very basic but durable rack set up. I'm personally not a fan of the way the barbell holders are set up, being 4 pegs. I also believe these safeties wouldn't hold up to much dropped weight or too many heavy rack pulls.

Enjoy using these at a local gym. They've been around a while and stand up to use, but I can't specify on price/ accuracy.

My custom DIY version of a plyobox has been laying a tractor tire on its side. This has been handy for power stairs training. Great value being free, but takes up a lot of space and not a lot of height options.
