They work, but they’re made kind of eek. Stuff doesn’t line up perfectly - but the bigger issue is lots a very sharp spots. The metal mesh stuff sticks out in lots of places on 2 out of the 3 that I got. I used some tools to press it down and might put hot glue over another poky part. Basically if you’re handy and have time to work with them for a minute they ok. Definitely wouldn’t recommend them for kids to use unless you work on them first. ￼
