"This one is not a must, but it works in very small cracks" 03/04/13

If your climbing where they only have small cracks, you will need this. But its not really a must.

"The Backbone of Your Rack" 04/14/12

Safe, bomber if placed right. The numbers 1 and 2 are surprisingly tough and held up well on tiny placement in Yosemite. They're light, cheaper than other pro, and fairly easy to remove. A key part for building your rack!

"Bomber pro!" 01/12/12

When I first started climbing, I was skeptical of these guys. But now when I see a great nut placement, I have no doubts that it will hold. These are essential for almost any trad climb and don't weigh much at all. Much of my climbing is in Eldorado Canyon where these are simply a must have. I don't think that there is anything to be improved upon with these nuts. Black Diamond has their incredible reputation for a reason and these nuts will last you a lifetime and will always keep you safe. These do require more thought than a cam placement, so if you are new, find a place to practice placing various sizes of them.

"Awesome for any rack!!" 09/20/11

I picked come of these up as the first couple pieces to my trad rack and they have been a staple ever since! The placement is as bomber as you can get and pops out super easy. The best part about these is they won't break your bank! I bought two at a time and never even worried about the price!!

"Some of the best nuts on the market" 09/16/11

These are the classic nut design, awesome and bomber placements and backed up by the reliability of black diamond. Very nice pieces, a must have for any trad climber. They seem to be easier to remove than a lot of other brands (notably DMM) which can make it a lot easier on your second, and overall this design proves that simple can be extremely effective!

"Your first trad purchase!" 02/24/11

I know how it is. You've gotten the trad bug (or maybe even the top rope bug - those are itchy too) and want to start buying gear. After you've covered all the gym basics you're going to want to start building up your rack.These nuts are a great first piece of pro. They are high quality, and fit snugly in just about everything you'll come across. Plus, if you're building a rack on the cheap you can buy a couple every pay day and still not break the bank.Note: the two smallest sizes are really only useful for bodyweight placements in aid climbing. They aren't really built to take a hard fall or build an anchor. Use a smallish cam for that. All of the rest of these guys are bomber though!

These stoppers are a must for any trad rack.

"perfect for its intended use" 12/27/10

these are the classics! theres a reason theyre so basic, because they work! i do find they work best when in smoother cracks as they dont catch well on small bumps, but learn where they excel and theyll never let you down, i will say ive left two behind, but a stuck nuts is better than a slipped nut!

"Not as good as they should be" 12/06/10

Stoppers have been around the block and can be spotted on nearly every rack at sometime or another. I picked one up as a booty. It fits in decently with my DMM Wallnuts (much better than stoppers) but just isn't quite as good as it should be. Due to its design, it never seats quite as well as the wallnuts do and has a tendency to get stuck more often. IMO go for the wallnuts and leave stoppers for booty gear.

"Durable, Cheap, Salty" 11/12/10

Black Diamond consistently designs really great burly gear. The stoppers will stand up to the abuse of somebody that is better at falling than climbing. They generally fit well, though I feel like offsets like the ones produced by DMM tend to fit better in pockety placements and runneled cracks. That said, I have these on my rack.
