Product review (5 stars): ... lot of time and energy into making it loos nice, then when you chisel out for the plates
I always struggled with doors because I'd put a lot of time and energy into making it loos nice, then when you chisel out for the plates, it looks awful. I got this set of jigs and fumbled around with it for an hour, and once I got it all figured out I did 2 doors back to back (identical setup) with no issues and it was perfect.

I actually went and bought the other 2 packages of templates from Milescraft. Those were expensive, and probably not worth it. But, having the right tool/template when you need it is sometimes worth it. My biggest complaint with those is I have NO idea where I'm going to store them. The case for the system itself is pretty cheap and not worth its weight in plastic, add another 30 or so templates and you have a real mess. Maybe have to get a cheap toolbox and dedicate it to this system.

The only issue I had was that the jig was not in the same position as the existing manufacturers mortise. So what I ended up with was 2 overlapping rectangles, one the correct size, and one incorrect and offset by about 1/8". Luckily the weather seal hides it and it's not a big deal.

Very sturdy, better than the plastic template alternatives I've wasted money on before. Should have this as my disposal for years to come without issues.

Almost forgot...I was missing 1 screw for holding the templates together. $1 and a Menards run should fix that, just inconvenient is all. For what this bad-boy costs, you'd think a bag of screws would be your last worry.
