Review: Great for measuring door margins. - Used these on a job with very strict regulations on fire doors, very accurate and fits easily in your pocket or tool belt, a must with high end finish jobs. 👌🏻 Found the best way to use it is have the slider set away from the door margin until its inserted then slide it to the door for a more accurate read.
Review: Alright - Fair item, I was expecting a bit more functionality then this but its dine not bad. The compatibility is fairly good as well
