Nice assortment.
Size: 304Pcs 24-sizes
Nice of assortment for general use with motorcycles, farm, equipment, and vehicles. I prefer the stainless ones over standard steel as you don’t end up with a rusted clip on there especially when you’re working with bolts or axles that are already stainless steel. You don’t wanna put a regular steel one on there and have the rust. It’s nice to have a good assortment last for a long time, and they seem to be a high quality.

Great selection of sizes - good quality
Size: 120Pcs 6-sizes
This is a very nice assortment of cotter pins. The last set I purchased (locally) cost almost twice as much and it came with fewer pins. I'm always needing to replace a cotter pin when I work on my yard/gardening equipment and this kit always has the size I need. They are also quite durable. I use these to hold the wheels onto the axel of my utility trailer and they have never failed even though I'm pretty rough on it. They stay put and don't break during use. There isn't much to say about how easy they are to use. They're cotter pins - just push them through the holes and bend back the tabs and you're done.

Nice to have around
Size: 120Pcs 6-sizes
Decent set. I probably won’t need more than a couple over the life of me doing wwwkwnd warrior stuff…but figured it was a nice set to Keep around and probably not much more expensive than running to the hardware store to buy a couple of them. So why not?

Good. But, not goodest. But worth it. Just wish they were longer. For versatility.
Size: 304Pcs 24-sizes
I give it a 5 for quantity, but a 4 for length. Would rather a large set that can go up to 3/8" and all minimum of 2" long like a 1,000 piece. Can't find that assortment. Pretty broad set though.

Needed 1 particular pin for my tractor. This kit was the same price as the single one I needed, came with the size I needed, and now I have 119 more for future projects.
