I bought this a few years ago thinking it would be convenient for easily measuring height. I measured my child's and my own height a few times according to the instructions, but for some reason, there was an error of about 3 cm. I suspect it's due to improper measurement, but since all family members were measured about 3 cm shorter, I assumed it was due to ultrasonic measurement interfering with something. Now that there's no longer a need to measure height, I'm listing it for anyone who might need it.
I never figured out the exact cause of this error, but it has been tested and is in working order. Please consider purchasing after reading the above information carefully and agreeing to the conditions.

Batteries are not included. You will need 3 AAA batteries. Also, there is a small tear on the box from when it was opened. Please refer to the 13th photo.
