There is nothing sweeter than placing a bottleneck nut into a constriction. Cams may be amazing and incredible, but I always feel secure placing a nice nut placement. I use sizes #5-9 more than any other size.

Bomber. Perfect sizes, color coding isnt bad, nice curve and tough wire. What's not to love about the stopper?

What can I say. No bells or whistles and does the job!!!

I bought a couple to replace the gaps in my rack and really like the color-coding. They're also prettier, I almost hated to place and scratch them. Okay not really. Like the guy above, stoppers are the foundation of a rack. I will trust one before I will trust any other pro. Make sure you have the full set, and the price is right on these.

These were the first bits of pro I ever purchased. I bought the 1-13 set when I was starting out and they are very solid. Personally I prefer the ease of placing and cleaning cams, but everyone needs a set of stoppers, and when set right stoppers are super strong placements and yet so lightweight. I don't really see much difference in these stoppers compared to most others of the similar shape and material. I find the useful range of these stoppers to be 4-13, though I really don't prefer placing anything lower than 9 because 9-13 have the opening, and I find I can remove these with my nut tool easier. I have had to clean these even after being weighted, and I've always been able to remove these without having to damage the rock or the nut. The color coding is helpful. A quick note according to the tech specs on this page it says "7/8 2kN", this is obviously meant to be 1/2 not 7/8.

Lets be honest: when it comes to protecting a fall, an aluminum wedge is the same, no real matter who stamps their name on it. The real challenge is in knowing how to place these so that they work right. So, practice your placements before you go out and start leading. My bottom line: if you can place them well, stoppers are the best removable protection around!
