Review on Stay Cool with the Comfort Zone CZ6C 6-Inch 2-Speed Clip-On Fan: Set of 2 Fans in Sleek Black Design! by Dianna Kay

Bad. This is the 3rd time I have ordered fans in 6 months to be returned 10 minutes after use. DO NOT BUY IF YOU NEED TO ATTACH IT TO A VERTICAL OBJECT. You don't have a clutch. It took less than half an hour for one of them to fall and crush one of my seedlings. Ten dollars missing. Luckily it was only one. You don't hesitate either. Too many fans have useless double words for you to think it's hesitant, but it's not. It's just a bad product.
