Fantastic product has worked reliably, it is stable, solid and high quality- works great on my TD30-module and rack, you can easily use on a stand too. Well worth it and cheaper than other inferior models available online. it provides a good deal of variables/angles for modules allowing sloping or straightening(levelling or slanting) of either audio interfaces, modules and even some sampling pads, or Roland Octapads. It is a good all round clamp with a very handy base plate and a geared grip joint that won't fail or slip with heavy duty weight on it-I've tested it many times and used it daily on tour without issue.
