Very pleased with my Hilo. It's on a Soul with a 27.2mm seat tube.
Was a little concerned about the quality before buying but I stopped worrying when I received it. It has solid construction and good finishing. There is little side to side play.
I use the cable remote and it works adequately. I would say that the remote and the cable are probably the weakest part of the kit. The cable has a bit of friction to it, so the lever action isn't that positive. It doesn't affect the operation at all.
I have been using mine since the beginning of the year with no problems at all. It has stood up to some medium sized crashes in that time. I plan to service it after the winter (something you can do yourself). I have just realised that I have never topped up the air pressure because it has never needed it.
Overall a very good and reliable bit of kit. Considering I was able to pick one up for less than £130 at Wiggle I would have no hesitation in recommending it.
