I bought a large pack of the mini hooks to hang strings of mini lights around my daughters' room. The walls were clean and smooth. I followed the directions exactly as directed on the package. I used 1 hook every six inches to ensure that there was not too much weight even though the strings are very light weight. I waited two hours before hanging the lights. Within a half hour over half fell off. I bought these particularly because they were small and clear so they wouldn't look out of place.
I am very disappointed and would not recommend this product. For price and the reputation of Command I expected better.
