This dovetail mount is well made and it was straightforward to replace the original dovetail mount on my AZ-GTi with this one. It grips the dovetail on my telescope a lot more securely than the original. The matt black finish is a good match to the colours of the AZ-GTi.

The adaptor comes with no instructions. But fitting it was pretty easy. On the existing adaptor the screws are covered by a thin glued on metal plate. I warmed it up with a hair dryer to soften the glue, then prised it off using a flat blade screwdriver. It came off ok and left no gluey residue behind. The original screws need a Phillips screwdriver to remove them. Then the four supplied hex bolts can be used to fit the bracket on, they take a 2.5mm allen key. The actual dovetail adaptor then fits on with two more supplied hex bolts, which seem to be imperial bolts - I think 3/16". I only have metric allen keys, but I found that a 4.5mm allen key fit them good enough to tighten them securely. Fitting the adaptor was a 10 minute job all in.
