Rated 3.0 out of 5.0 by Jim Right angles are not exactly 90 degrees...
When I bought this adjustable T-square, my thinking was that I could have a T-square for use at home -- for all the reasons one would want a T-square (such as marking lines on wood which are exactly perpendicular to the edge) -- which could also collapse down to only take up space along a single dimension, making it easy to store. As for the second part, storage, it's aces!
The problem, however, is using this adjustable T-square to draw those lines which are exactly perpendicular to the edge of a board. On most of the lines I've drawn where I've _wanted_ them to be 90 degrees from the edge of the board, I've found that few of them are. Until I can trust this product, I've had to test it at home, and I've done so by making additional measurements, with different tools, after I've drawn my lines with this tool, and, for a line drawn along a 4-foot section of board, where the line was supposed to be perpendicular to one edge, which would make the line exactly the same distance at both the top and the bottom of the line from the parallel edge, I've found differences in distance by as much as 0.5 inches!
Now, it's possible that I simply had purchased one of these which was faulty, but that most of them are good. It's also possible that this particular product is no good, but, for the most part, all other adjustable T-squares are simply fine. I am convinced, however, that one will encounter problems like the one major problem I encountered if one decides to purchase ANY adjustable T-square, of any brand, no matter how "well it checks out in the store".
Tomorrow I go to purchase a T-square which is not adjustable, which is permanently in one o' them non-89-degree right angles!

Rated 4.0 out of 5.0 by GS A solid purchase
Definitely a solid and wonderfully adjustable straightedge and square. It can be a bit frustrating on large flat surfaces because of the edge that was made for drywall, but overall it has served me very well.

Needs and better and quicker way to lock in place. Also the edges seem hard to use too rounded and not deep enough

The T-square is very basic, but done right. I experienced no problems with misaligned guides. The only issue is that the guides are machined so close to tolerance that they get stuck in position. If the manufacturer chose a different groove shape, such as a prism, instead of square grooves i think this would not happen. However, just a tiny bit of oil or a little elbow grease and your good to go. I think this is a good value for anyone who just needs a T-Square, and has no need for a level.

I'm going to keep this compact T. Folds up nice and it locks in as a perfect square. I will have to sell my other fixed types because they will never get used again.

Rated 5.0 out of 5.0 by Betho67 Exactly what I needed for the job!
I needed this tool to find the ceiling angle for the sheetrock across the face of my fireplace. Awesome!
