I have no idea of the accuracy. I mean, the ultimate purpose of a tape measure is accurate measurements, so the thought of an inaccurate tape measure throws me into a spiral of existential doubt. What is the reality if my kennel isn't actually 2ft 10-5/8in wide? Anarchy, I say! So I just trust the machines that make the gauges. nice touch because to hell with the metric system and its overly efficient simplicity πΊπΈ It's sturdier than most, but when you measure the height of the ceiling it can wobble a bit, about 12 feet when the tape is cut in half is folded (builders know what I mean know ). For some reason I thought it had an auto lock so I was disappointed when I found out I was wrong but I guess I can't blame the roulette itself. The only real problem I had is weird: it's insanely easy to lose. The case has no bright colors, patterns, or anything special. He can sit right in front of you and you swear you lost him. Funny but true.
