These are great for how much they weigh but they are small diameter. I don't use these for dumbbells but for my loadable ez curl bar. I want to have lots of weight options for my ez curl bar and this gives me lots of weight combinations for it.

This is really cool device for training grip. I like the feel of it and how easy it is to have anywhere in the house. I can just sit up at my desk and use it or use it in gym etc. I like this pro version with the pre filled synthetic pellets instead of actual rice. Also no mess with this like a bucket of rice.

This is great option to add weight or another thing I have done is use it to jump between weight stack amounts. Adding weight overall to the stack is the main use for it. This is the original which is 6 inches long 2 inch diameter and is 8mm. Be sure to check if you have 8mm or 10mm stacks before you order.

This works great for me to stretch calves. After tearing achilles this is even more important for me.

Well made and good quality. I love the length as it works great for exercises like face pulls. American made by belt fed for rep.

This is inexpensive from amazon but works well for my purpose. I am putting 10 and 15 pound rogue dumbbell bumpers on it for the purpose of using with my loadable ez curl bar and this makes for great storage for that under my ez curl rack.

These are cool and super useful for me to get half jumps on my machines. I feel you do need two so you can get actual half jumps on the 10lb weight stack plates.

If you need extra carabiners these work well. I have some rep ones that are very similar and I have some rogue ones that feel very heavy duty but again bang for the buck these are good.
