Ohm

Uses the Ohm 2.0 with a 60 kg weight difference; their partner takes a lot of falls and it's totally fine.

At 110 lb has belayed a 210 lb climber with an Ohm 2 and it worked fine, standing back just enough that it bites quickly whenever they aren't paying out slack.

Uses an Ohm 2 indoors and out with a 60-70 lb difference; they still come up a bit on overhangs, and it mostly helps with lowering.

Has an Ohm 2 and describes it as a steel wedge that makes everything a hard catch; wants the smoother Ohmega.

Was scared of belaying their 25 kg heavier partner before getting the Ohm 2; now they don't fly up at all and he says falls don't feel like a hard catch.

Got an Ohm II for a 65 lb weight difference, but their husband hated the hard catches and they no longer use it.

At 110 lb, has the Ohm II and uses it regularly; their gym also has a couple that people use without much trouble.

Regrets buying the Ohm II for belayers 40-70 lb lighter: it grabs too hard; would suggest the smoother Ohmega instead.

Got some harsh hard catches on the Ohm II and is going to try the Mammut Assist instead.

Bought the Ohm II after being shot up to the clip by a partner 84 lb heavier; great for the belayer, but it short-ropes and gives him pretty hard catches.

Uses the Ohm II with a 70-90 lb difference on a 9.5 mm rope; standing about 3 feet back and stepping under it while feeding a full arm's length for clips works once you're used to it.

Uses an Ohm 2 with a 50 lb weight difference and it really helps.

Moved from their original Ohm to the new one, which is better but still not great.

Their only real issue with the Ohm is it engaging on climbs that start very steep right at the first bolt, where the rope bends sharply.

Uses an Ohm as a heavier climber but sometimes gets short-roped clipping because it engages if the belayer stands too far from the wall.

At 180-185 lb with a partner around 100 lb, they greatly appreciated their Ohm and never climbed with her without it.

Belaying a partner 50 lb heavier with an Edelrid Ohm, it catches everything so they barely leave the ground, giving very hard catches.

Has used the Ohm for a big weight difference between climber and belayer; says it is good too, though it can short-rope the climber a lot.

Uses an Ohm when belaying heavier partners who will hang a lot, finding it takes a lot of weight out of the system and off their harness.
