Title: SAFETY HAZZARD!!! DON'T BUY!!
Review: I agree with everything everyone else wrote about these devices not working. My daughter was 8-months-old when she figured out how to take them off and throw them. What wasn't mentioned was the huge safety hazzard these plastic pieces pose. After months of throwing them off and chewing on the wood anyway, they caused my daughter to have a pretty bad fall. One morning, right in front of me, my daughter crawled up and held onto the plastic railings. The plastic came off the railing as my daughter was holding on to it, and she fell backward to hit her head hard on the rails in the back of the crib. That was the last time it was on her crib. Also, since there are four plastic pieces that aren't joined together, there is risk of finger pinching.
Is the review positive or negative?
