We purchased 2 of these to disinfect chairs, just after 30 days one sprayer will now only spray if it is plugged in. I have no way to contact the seller to find out if the battery can be replaced since it seems to not hold a charge.Works good but with time the spray would only shoot out and not mist. Still use it and works fine otherwise.It stop working properly after a weekClogs up must wash after every usrAfter I had the item for awhile, I decided to use it. The trigger got stuck and would not shut off. I kept trying and finally it just stopped running. I have no idea why.It stop spraying. No information on product. Purchase 2 and both of them stop working after a few months.This sprayer was easy to use and it wasn't to heavy when fullGreat for sanitizing with spray
