Input:
Used it about three times, then it clogged up. Read advice on how to unclog it by using hot water and vinegar and tried to salvage it, but it still didn't work for me. Got another cheap knock-off for Christmas from a family member, and that one clogged up quickly, too. Waste of money for both of them. Also, even if had been able to unclog it, I don't want a sprayer that is so much trouble that I have to keep unclogging it after I've used it. Into the trash they both go.
