PEC Square
Ordered the PEC square. Came promptly and packaged well. Very square. I was super happy with the square until I pulled the ruler out of the housing. Could not get it back in. Finally 45 minutes later it slipped in. I thought ok I won’t do that again. I’ll just keep it together. Then this weekend I accidentally slipped it off. I can’t for the life of me get the 2 to pair up again. I have multiple combination squares including a Starrett so while I’m not an expert, I kind of know what I’m doing. Don’t know if the internal mechanism is fouled as that’s where the blade is scratched badly. Don’t know if I just got unlucky. Don’t have time to figure this out each time.

Good square for a good price
These pec blem combination/double square offerings are overall a good deal for quality tools. Cosmetic damage aside, be careful to keep the square body and rule clean and clear of dirt & grit. A well maintained pec square will last a lifetime, but a frequently used pec square that is not cleaned/maintained will end up with a buildup of dirt and grit that unevenly wears down the bearing surface for the rule - resulting in an out of alignment square. Be sure to regularly check your squares for alignment, so if needed they can be adjusted/tuned before the square is significantly out of alignment and more material removal is needed to re-align the square. With frequent use, my ~2 year old pec combination square was out of square. With a needle file to even both ends of the wear surface of the rule and frequent checking, I was able to re-calibrate it to be square again. Unfortunately there isn’t a lot of material left if I need to file it down again in the future.
