Review: Robust, good quality. Works very well. - Very solid and well-built kit. Nicely adjustable. I was able to put mortices in 3 doors very straightforwardly and cleanly.

### ⭐⭐⭐⭐ Ease of use. Time saving.
*by G***Y on 3 February 2026*

Jig arrived next day, well packaged handy plastic case, Assembled the jig. The jig appears to be of good quality materials, only down side is that the bolt heads are not a tight fit in the casting but this did not affect the assembly. Marked out door, installed the jig onto the door and drilled out for door lock.time taken start to finish 15 mins so much easier than drilling and chiselling into a blind hole. Very impressed price, ease of use. Would have given 5 stars if bolt heads fitted tightly in the casting.
