Charge only lasts 1 day with minimum barking

This product WORKS!! My very mouthy pups, learned quickly to stop barking....HOWEVER, I have had it 4 days and had to charge it 2 times already. I have turned it off after each use, and also the dogs have not barked hardly at all with the second charge, yet its still dead within a day. If it lasted the month or two like stated it would truly be a miracle worker, however you may as well charge it every night which is very frustrating and time consuming.
