Build Quality
Impressive. The device shell is composed of a metal made ring / sleeve and a rear plastic enclosure that provides excellent build quality and durability so the unit can’t be bent or broken easily. On the front face, you have a pretty large display panel with three control buttons.
Operation
In comparison to a standard traditional measuring tape, this product does not have any metal strip, but a built-in rolling element wheel you place on a surface. To measure a simple, straight, none curved distance between two points you need to power the unit via the middle power button and use the LED light marker to set it on the start point and just roll it between the two points until a measurement is displayed.

Operation buttons
The main button located in the middle of the device is used to power the unit and also reset existing readings. The history of previous readings is also saved in the device memory and can be accessed by browsing with the right/left arrow navigation buttons, that are also used to switch between 4 types of measurement modes / popular scenarios.
4 types of measuring Modes:
- Straight line (Distance between two points on a straight line).
- Two corners (Distance between two corners).
- Right corner– straight line.
- Left corner– straight line.
- Diameter Measurement (for Cylindrical Objects).
Messuring distance between Corners:
To measure distance between two corners, for example a window you simply press simultaneously press both navigation arrows and the unit enters the “corner measuring mode” and automatically subtract the radius of the device during the measurement process.
