It's easy to use, easy to preset & the students responded very well. I've installed this on my school bus. A miracle in a month, the kiddos now monitor their own noise level! I love it!

love it! Looks great in a boys room !!!

Exactly as expected

I am a school principal. We were having serious sound issues in the cafeteria and nothing seemed to work. My hope was that students would self-police if they could see where they were with the sound. IT WORKS. We have been using this for a entire semester and it has been amazing. The issues in that room were once out of control and now, I never have issues past when they hit red light and cannot talk for 5mins. Works great!!

It was gift for my husband who is a teacher. He uses it daily in his fourth grade classroom on and loves it.
