This thing is pretty sweet and super smooth. Best for tricep work in my opinion. I found it feels a bit awkward for me doing bicep work towards the bottom of the movement, but could just be me as well. I only rated it lower on value b/c of its higher price tag and somewhat limited use, but don't let that fool you. It's a quality piece that feels great for the movements that it's intended for.

I’m not a fan of these particular mounts as they’re the most permanent ones offered. This is fine if you have a dedicated upright to mount these to that you don’t want to move the location or use the rack for anything else, but I don’t find that to be the case for most. Better off getting one of the mounts that’s more portable, like the Darko Quick Mounts.

These mounts are my preferred way to mount my Voltras. They easily slide on an upright and take no time to adjust. I have the original version which is a bit bulky but they’ve released an updated slim version. I have found that the UHMW inside can scuff lighter colored uprights some.

These things are cool. Super customizable, affordable, and they let you easily give bland equipment a way to match your gym aesthetics.

These are pretty sweet handles, simple in design but super versatile with all the mounting points. They are a bit on the pricey side, but they’re from a small made in USA manufacturer with really nice finishes. The grips are plastic to keep cost and weight down, they provide adequate grip but metal would be preferred.

These balls are great! I was sent one for a promo and liked them so much I bought the whole set. These things are pretty indestructible compared to regular medicine balls. The fit and finish on these is also top notch. They're a bit pricey for what they are, but you won't find others like them on the market. The biggest downside is that there are only 3 sizes and all are relatively light. Would like to see heavier versions.

I had this for a bit before selling. The concept is kind of cool, a preacher curl set up with out having to have a dedicated piece. However I found the execution wasn't anything exceptional. What I mean by that is you could use other things you already own to brace your arm against and the set up would be much easier. Personally I feel like doing one arm preacher/concentration curls using an incline bench would be better and save you some money.

I have the original Kleva version. This is a nice attachment, well built, lot of grip options, a landmine or cable attachment point, and extremely light.
