I ordered 2 of these and they both have their insertion pins are at a slight angle (not straight). They still do the job on my Inspire Fitness SCS (10 mm dia. X 110 mm long).

This is great. I have a relatively light stack, and I needed to add 25 to 35 pounds for heavy back pulls. Feels like it is made from quality material and does the job. I wasn't sure about the pin size, so I got the smallest one and only needed to wrap a little bit of electrical tape around it so it fit more snugly. If you are a powerhouse and need to add serious weight to your puny stack, buy this right now and go pump your muscles you gurley man!

Much nicer than I expected it to be for the price. Works exactly as it should.

Perfect. Never falls out. Handles all the weight you can add to it.

The 110mm pin works much better than the 80mm pin (which is too short for most American gym machines). Product does exactly what it's supposed to do!

First off, know the size of the holes of the machines you’re using. Simple google search helps, I learned Planet Fitness USUALLY has 8mm machines. This tool is perfect, low price and good quality! Can be too big/long for some machines so use common sense on where and what you’re trying to use it on.

Not durable. Unusable after less than one month of use. Only a 30 day return window.

This weight stack pin works fine but I've marked it down because the small pin that inserts into the stack started to bend after a couple of months of use with two 45lb plates making the product a bit unsafe. I've now purchased a different brand to try.

Despite me buying the longer/wider of the two pins, with only a 5 pound plate added, the entire assembly including the plate fell out on the first rep. Obviously, a heavier plate would only exacerbate that issue. Further, the collar provided barely fits and is a struggle to put on. I don’t have time to waste trying to shimmy a collar on in between sets.Immediate return.
