A versatile belay plate, works excellently in guide mode and as others have mentioned the addition of the extra hole to help release it has made a world of difference.

I find it very smooth to use, perhaps too smooth for some and is considerably less 'grabby' than others that I have used - I've used it happily with ropes from 9.1mm to 10mm though I find attention is required when using the smaller diameter ropes.

Hard not to like these, excellent for sport climbing with a nice wide tape so no turning of the karabiners. Lovely gate action and confidence inspiring build quality.

Don't tend to use them for Trad climbing as a lot of them ends up weighing too much on the harness with the other gear.

These are excellent nuts - I find that they fit and seat well giving good protection, the scoop and flare allowing then to sit well in a variety of placements.

I still find that at the lower end WC rocks fit as well if not better in some placements but the only serious contender in terms of performance I've found are the Metolius Ultralight Curve Nuts which are also excellent.

Pros:
Anodized (personal preference)
Versatile
Stiff wire

Cons:
Can be tricky to clean - can sit too well!
