The Laser Sonic by Petzl goes in smoothly. You can clip your draw and turn the screw while being clipped in. So if you fall, heaven forbid, while placing the screw, which can happen, with this screw there is a chance you will be caught if your screw holds. In good ice your screw doesn't have to be in very far to hold a fall, especially with some rope out. You can also take these screws out WITHOUT unclipping them, so they are clipped into the rope until you clip it into your harness, then unclip it from the rope, eliminating the drop possibility. When placing this screw, once it is established and I know it won't fall out, I grab the swivel with my thumb and forefinger and spin it in. They go in like butter! They can be a bit unruly to rack due to the swiveling clip in point. To limit this unruliness, stabilize the swivel when racking. Happy climbing!

I used these in kandersteg last weekend along with BD turbo express and I feel these are better. The BD's bite into the ice quicker but, these have an overall easier placing. Much easier to use with gloves and one handed, also how the head is angled away from the ice. Your second doesn't have to worry about dropping them because they can stay clip in. As a bonus they come with petzl ice flute for storage and racking. Definitely buy these over any other ice screw.

Light, doesn't have an annoying handle mechanism like the Grivels, and is much easier to operate with bulky gloves than the BD Express. Comes with the cool ice flute thing for storing and racking. I think the best feature is that it's easy to use with bulky gloves, but the reduced likelihood of dropping a screw is pretty sweet too. Worth the money.

Not only do these screws go in easy, they are the ONLY screw on the market that you can easily place while clipped in.

This means that you cannot accidentally drop the screw when placing or cleaning your pro.

These screws are great screw for placing and removing really fast on the ice. Racking the swivel heads is a little funky, but you can get used to it.

If you're used to BD screws, either the turbos or the express, or any other screw, these might seem a little weird at first. The integrated hanger/thumb screw allows for faster placement and easier removal, eliminating the need to unclip before you unscrew them from the ice. These are great screws!

Sets and cleans easily thanks to rotating head. Can fit 2 crabs in the head which is a bonus.Don't buy from Backcountry, their service sucks, send the wrong products then not reply to emails. Go elsewhere
