Small, compact, clean and worked thanks thumbwheel in any desired position can be fixed. Big plus compared to many other flash shoes is that even Canon Speedlites with rubber sealing sleeve on foot flash (600EX-RT with me) without any problems and can also be locked fit. While there is no front hole for the Canon-locking pin, but this appears to be a snap in front of the Phillips screw. However, the plastic housing with the thumb wheel works quite thin and also consists of 2 parts with a seam. With a relatively large Speedlite 600EX-RT as Canon (or 580EX etc.) it seems to me, therefore, as latent "breaking point". One can also find good, because with greater force then perhaps not break the hot shoe. But I had the thing but rather from solid metal (aluminum). Therefore 4 of 5 stars.
