This is pretty hard to get perfectly square with the track. After adjusting it several times and cutting all
4 sides of some plywood each time, I always ended up with 4 uneven sides. I concede its probably me, not the tool. Nonetheless, this thing takes some effort to attach correctly.

I recently purchased the simple square with a 2' length of track. Setup was pretty simple, squaring the base with the track and tightening the 4 bolts. Of course the beauty of the TrueTrac system is that you can line up the white strip with your mark and cut without any further measuring or offset blocks. The square just adds one more dimension to the system. Saves time and improves accuracy, what more could you ask for.

Allows for positive control.

Product works as advertised but could be improved. Tool is rough around the edges and would be more user friendly if you didn't have to screw it on the track every time you want to use it. I would recommend rounding the edges and maybe anodizing the tool to make it not only look better but feel better while using.

I purchase this squaring device last year. It was extremely easy to set up and can be quickly used. I use it on a longer track now instead of the shorter one that came with it. It stays true once it is set up due to the dovetail connectors. A excellent product for my setup. I use both a M18 Fuel 6.5" saw and a corded PORTER-CABLE 423MAG 15 Amp 7-1/4-Inch Circular Saw, LEFT HANDED with dust collection for my system.
