These really work.

Allows my child who is only just over half my weight to lead belay me with ease, including on big falls. Don't understand how they work but they're magic.

Only downside is that it can accidentally engage if you pull rope through fast, but a quick flick from the belayer resolves.

Great Device, easy to use and very effective.

Simply put the Ohm makes the climber artificially lighter by introducing friction into the system when they fall so less upward force is felt by the belay and they don't get pulled up to the first clip.

2 improvements are: It could be made clearer which side should face out/up. There are markings but I don't like having to check closely while im clipping. It should be made more obvious. I also think they could improve the design so it is slightly less grabby when you pull rope through quickly.

Safe climbing

You have to be really calm during the lead beacuse if you pull the rope fast to clip, the rope it will get stuck, similar to a bad belayer.

Its not the belayr fault, its how the system work. Well,if you are pulling the slow, maybe its the belayer fault.

I recommend it to everyone with weight difference

I bought this Ohm to be able to climb with my girlfriend, we have around 50 kg weight difference which is much more easy to handle with Ohm! I know a diet would help better but it would be good for the future as well!!
