I've used this at a local RI gym (TSP). The movement itself is nice but the machine hasn't held up really well over time. Arsenal is also very overpriced.
Not a fan of hex as they get huge as you go up in size. For the most part all brands are super similar and it's just a logo swap. Prefer a straight fully knurled handle as well.
Had used these on my old RML set up. Not a huge fan of the design due to the amount of real estate they take up on an upright and their overall weight.
I actually really like these plates. Very similar to the Ivanko spokes in fit and finish. Wouldn't buy them new but if you can find used, they're a good buy.
This thing works really well for the intended purpose and is priced pretty well. Looks a lot better than bands or shelf liner and has some custom colors.
These are nice lightweight high quality carabiners. Prob not monetarily worth it to buy separate, but nice they're included with some of the Voltra pieces.
