I fell on the #3. It was in a shallow flared seam. The ball rotated in the groove of the nut and held fast. The piece was hard to clean, but held the fall like a champ. The 2 and 3 stay on the racking biner with my small stoppers, rocks and microstoppers. Even the larger ones will go places that cams will not. I do not consider the smallest size worthy of lead falls of any size, however.

Perfect for small cracks where your C3s can't protect you. Easy to place and remove. It's like a camming nut!

These are quite possibly one of the coolest things I've ever used. Super easy to place and clean.

a huge fan was on Arrow Place at Red Rocks using my partners Ball Nut. Better really for aid and granite routes, but we find our purpose for these bad boys in the sandstone at times. A savior at the start of Arrow Place where cacti wait patiently below the crux decking move.

Definitely a great addition... I wouldn't use them as a nut replacement, as I don't feel they are as secure as a good ole chock, but they definitely protect when nothing else will, and with a strength rating for their size that puts other pro to shame. Their construction and design seems rock solid, just be extra cognizant of each placement as with any piece... Its usually not the gear that fails, but the rock around it.

I've used these fro about 15 years. I've gotten out of a lot of uprotected positions with them. You will have to watch the placement and make sure they are set correctly, but they are usually very solid and I've never had one pull out when fallen on or weighted.

These are a great addition to your box of tricks.

I bought the 3 smallest sizes for aid climbing and I have not really used them that much. I would not really want to take wippers on the smallest size. They can be tricky to remove if heavily weighted because of the soft material on the "sliding ball". They are obviously great for small cracks and for podded out pin scars. They are definitely not my "go to" piece but a nice addition to a standard free or aid rack.

These are great alternatives to pitons and give a greater strength rating over smaller camming devices. I use these a lot. More than I thought I would.
