I tossed between X Pro and Big Red but decided on X Pro. On the X Pro, the fonts are very nice and legible, but the rest of the design isn't that exciting. The body is thin-walled aluminum tubing and the ends are hard plastic. Most levels, even cheap ones, have the floor tilled. With the X Pro, it's the same aluminum tube. I can't imagine it took too long before a dent appeared on the underside that affected accuracy. Returned.
