In reply to Alan Pierce:
They were popular with some climbers about 6 years ago. I had one until it broke after about 2 years. I thought they were probably quite effective as an add on to training, but i quickly realised that I wasnt training enough to justify 1/2 an hour sitting with my arms twitching electronically. I think I once read that Paxti thought the same thing and he was doing about 10x the volume i was. I think they were better for the training programmes than the recovery ones, but these were not an easy option compared with actual climbing training. It hurt like f*ck. The recovery modes were quite relaxing in comparison but I'm not convinced it was that effective. You dont really hear much about tgem being used anymore so I guess other people felt the same.
