Great tape, saves time marking but has 2 downsides. The tape itself is flimsy and not very thick, so it cannot withstand stretching, allowing you to measure large areas. The second issue is that the button that keeps the tape from moving doesn't work very well and it's very difficult to stop where you need it (making it a bit more labor intensive), which doesn't help save time on pencil marks to save because I catch myself making that special pencil mark! Great marker for drywall! Works great if you are NOT in a hurry or not taking a lot of measurements! it's faster.
