Not one to normally spray about gear, I thought I might be able to contribute a little diversity of experience regarding this particular product. Have climbed in these on three continents up to 7000 m. No problem. These are some seriously rugged crampons.
I would, however recommend a crampon with monopoints for any steep (WI5 and above) waterice or tough mixed/drytooling routes. So, if you're planning on climbing some steep ice or rock and are short on cash, go ahead and spend on the Cyborg (also by BD), instead. That way you can switch out points and end up saving $.

This is my first pair of crampons so I don't have anything to compare them to; however, I found them easy to use as they make sense when I looked at them. Well thought out and well built. When I put the ABS on them for spring snow, it was the perfect set-up.

Great on neve, water ice, glacier ice. Haven't tried on waterfall ice yet. They fit well on Scarpa Invernos and Salomon Pro Ice.

I have used these crampons on solid ice, loose pack snow and on 70-degree packed snow/ice without any concern (except for my sanity). Make sure you take care of them, and they will take care of you...

These crampons are super tough and not
too heavy. I have not yet had the chance to use them. Will very soon. I'm wearing
Koflach Degre's and stepping into the Sabretooth's are very easy. Adjustability is great and the fit is good and tight.
You might have a problem if your boot size is greater than 13. I wear a 12.5 and the Spread bar is maxed out. Ok I hope this bit of info helps. So for the
price,durability and ease of use I give them 5 stars.

These crampons are awesome. I have the step-ins [pictured] and they work great with my La Sportiva glacier boots. They have great traction, the points are positioned in every spot where you would have your foot on a hold. I use them for mountaineering in the Pacific Northwest and I’m glad I chose these. Great crampons and I recommend them to any mountaineer (I’ve never ice climbed in them). Superb!

My wife, my son and I used these crampons for ice-climbing and alpine mountaineering. They are easy to put on even in extreme cold (single digits Fahrenheit); they stay on securely. We all used them with anti-balling inserts, which make a world of difference on alpine snow.

I have put these crampons to the test and they have passed with flying colors. When I attach these toothy beasts to my Vasque Ice 9000's, there is no ice field I can't handle, no matter how steep, going up or down. They slap on quick, come off quick, are completely solid, and unbelievably grippy. Try ‘em, you'll love ‘em.

Quality, all-mountain, step-in crampon. Perfect for the Scarpa Inverno.

Excellent crampon for mountaineering. Comfortable on snow with the antibot plates, very nimble on glacier ice. Front-point very well on steep and vertical ice. Quite versatile and relatively lightweight. One minor complaint: the paint job isn't real durable, so expect scratches and chipped paint if these are used in mixed/rocky conditions. Construction is bomb-proof, however.

Have had these crampons before, they are killer for mixed alpinism/low technical climbing. Haven't used this set yet, it’s not winter, but they appear to be up to BD's usual quality standards.
