This is the type of thing that you need to try out before buying. Many don't work well and/or break quickly.
Trying out before buying won't help for breaking quickly. I bought 5, (tried them all before paying) within an hour 2 were gone, within 24 hrs all 5 were broken. No where in the store did it say that I have to buy a tube of krazy glue with it. Luckily my wife was able to restore at least 3 of them.
