Ok, I'm genuinely mad about the ohm so take my review with a grain of salt. I'm rating it 3 stars because it does 'get the job done', but beyond that there's several decisions in the design that don't make sense and that are genuinely annoying.
I saw it being tested and publicized last year and was looking forward to getting one. Now that it's in my hands I'm left scratching my head as to why they built it this way.
1. It's far too heavy. There is no active cam device, it's just pure friction from fixed components. Why does it need to weigh more than twice as much as a grigri? There's no reason to have the entire body built from steel or for the 3/4" thick solid steel base. It's just kind of ridiculously heavy.
2. You must use their quick link at the dogbone attachment which, again, is heavy stainless steel. So many parts of this could be aluminum without compromising safety. It should also accept regular lockers instead of relying on a hardware store quicklink. Also, the dogbone doesn't have a rubber orientation guide, I could see the link getting cross loaded pretty easily.
3. They've fallen into the branding trap where the entire thing is Edelrid Fluro yellow, but with such heavy emphasis on rope direction they could have made far better color choices in allowing quick identification of correct rope direction. It's possible that a climber will want to use this 'pre installed' in which case it becomes tricky to quickly ID the correct orientation. Why not give the climber every chance to easily get it right?
4. It's just big. And heavy. I know, it's worth mentioning twice. It's hard to wrap my head around why a simple friction device needs to weigh this much. It feels like they could almost bring this down to the weight of a few aluminium biners
5. It's expensive. Why does it cost 30% more than a grigri. Again, no moving parts. No magic, just friction. It's far overpriced.
As you can tell I'm really disappointed and looking forward to a version 2 or for another manufacturer to get it right. All that said it does work well, it's just more suited for industrial applications (like permanent install in a gym) than belonging on a rec climbers rack. Something like this should be able to live in my climbing bag to be used on a whim, now I'll have to carefully consider whether to lug almost a pound of steel on the off chance I'd like to use it. I'd only recommend buying you have an absolute need for it.
