bought a pair and one worked as it should, but the other wouldn't bite into the ground and wind in, after a while trying we removed both to compare, and one had a narrower 'split' on the anchor screw so that was the one not able to wind in, a bit of action with a hammer and bar opened it out a bit more and we then had more success, though still not quite as good as the first oneBill Cove (11 Jul 2016, 08:48)
