Compared to Bridge City Tools that charges upwards of over $80 - $90... this thing is amazing. Perfect alternative to the super expensive ones, and dead on accurate.

Good fit and finish as shown in the listing pictures/video. Parts ride on machined dovetails for accuracy. Would like the scales to be imperial instead of metric but since it's not needed for most measurements there's no real issue. No instructions, but use the video and you'll be good to go.

This product just doesn't work bc it is not machined properly. I tried to give it a chance and now outside the return window. Once you adjust for the kerf of the blade, the whole thing locks up and you can no longer adjust for the thickness of the board. If you loosen very carefully, SOMETIMES you can adjust for the depth but it can take a long frustrating while. I have not gotten it to work after the first time I used it.

This is a knock off of the Woodpecker’s brand product. Much more economically priced but of excellent high-quality.

Great quality but the fact you need to tighten everything with little screws just doesn't hold it accurate. Cool idea but more of a novelty item than anything.

Instructions should have been included with this tool. They were not.

Very good fit and finish. Would buy again
