Reviewed by Millerman - 29th Jun, 2014 Simply great Simple and functional. I've used one as my main belay device for years and I love it. It does demand more care than asissted devices so experience helps. If a mate is working a sport route on a single rope and likely to be dangling around for a while I will use a Click-up or Gri-gri but for an all round belay device and for double ropes my ATC is my first choice every time.
