If you think these screws won't go in because they don't have a $30 spinning doodad on the hanger, think again. Once you get the screw started, press the circular cupped part at the center of your palm against the arched part of the ergonomic hanger. Then twist your arm in a circular motion, like you're waxing a car. The ergonomic hanger will spin in your cupped palm just as fast as the Petzl, Grivel or BD Turbo Express screws, but with an added benefit: Because you're pushing on the screw closer to the tube (i.e., not at the end of some long spinner on the hanger), more energy goes to pushing it into the ice.

Carrying a few of the Grivel screws is prudent, since they fit between features, but the simple BD ones will take you far. Plus, with the all money you save, you can buy a donkey or something to carry your gear for you on the approach.

Quality product. Vertical ice was sloppy one day and brittle hard the next but the screws worked well in both cases and I felt secure. I also had the fancy BD version with the folding knob and used both equally and with the same amount of ease/comfort.

These are great screws. They are a simple old style, and razor sharp, the will last a very long time thats for sure

These are great, very simple, reliable style, great for glacier and ice climbing. Great value and great quality.

Have only used for mountaineering on a glacier, and glacier ice climbing, but I was very happy with the ease of placement. After using both these and the expresses I would really say there is no need to get them unless you need extra fancy systems to skrew your ice skrews in. Not necessary at all though

Always keep a 22cm on my glacier rack for building V threads. Can't beat it for the price.

Black Diamond screws are the best hands down.

Petzl's may have all sorts of gimicks, Grivels feel a bit sharper when new, and OP screws might be a bit easier on the wallet, but for long term use, and a screw that keeps its bite year after year, these are the goods.

Really super duper screws - just really super

This is absolutely a winner for the ice screws. They are so sharp that they are very easy to put into ice. Nice Design and no problems found whatsoever. Definitely worth its money.

These screws are really fantastic for the cost - They really seem to stay sharp over time and takes little effort.

use them for glacier travelling and alpine ski-touring. just in case of a crevasse fall to secure your buddy. no weight and super easy to use.

Even if these screws place more slowly than every other screw, they are still great for setting up a belay or TR, and we save on the price. A nice price point screw!

easy efficient and safe. I love the simple design of these screw. No crazy bells here. Seem to stay sharp after many uses.
