Seems to work well enough

App seems to work well enough. Bought this measuring device on KickStarter. I thought it also did laser measuring over longer distances but in reality you can only measure distances by manually rolling the device over the length of the distance so the use cases are somewhat limited and pretty labor intensive because you have to roll the device the entire distance to get a measurement. Not sure the device worth $99. Maybe over time I will change my mind. I've only just unboxed it and used it for 20 minutes so far.

Love it

This pen is great for clean measurements- wish the program built a model and auto calculated area, but super happy with it.

Does Not Work

Installed the battery. No lights no pairing nothing. Nice box that it was sent in. That will keep it safe as the pen goes back to Thailand

Looks well engineered but if it does not work as promised -too much money for a pen.
