With such a solid construction, I had not really expected. The tablet can be attached stably by the clamping device. Since nothing wobbles. Genial I find the locks. This can not inadvertently get from the holder the tablet. The lock for the swivel from the cross to portrait is well thought out. The scaffold is made of solid metal, clean painted, and the locking screw (metal) runs in a metal thread. Thus, the holder can be attached to the tripod very safe. The finish of the stand is very well protected by the large plastic ends of the locking screw and the opposite arc. I use the part for mounting a Nexus 7 on my Manfrotto 055 XPROB tripod. The holder can be accurately pushed from the bottom of the center column of the tripod without having to turn up the volume the ferrule. saving time in building. Very good I think also that the holder itself (ie the part which the tablet clamps) on its underside has a 5/8 thread. Thus, the holder can be screwed directly onto a tripod or for example a Manfrotto Superclamp without using the tripod holder. All in all a super product whose price at just under 50.- certainly no bargain, but can not be justified in this quality quite. Nothing comes from nothing halt. Quality has its price!
