Review on TCR20362 Tracker for Teachers by Teacher Created Resources by Adrian Woodside

Bought 2 of these sets. 1 to teach my class about germs without paying attention and the second to share. I tested one of these and it worked well so I gave it to another teacher. When I went to class with someone else, the black light didn't work. It had brand new batteries but I tested them to make sure they were fine. the light was bad. I wanted to return it, but the return time was too short. I wouldn't recommend it mainly because the lights aren't good.
