Bark Control Collar with Spray

Have this Halband ordered for my Dachshund, because he barks permanently and the neighbor complains. Had it a week in operation, now it is no longer. Spray has been filled, the battery may not be empty after a week also displays nothing. The setting of the collar is too difficult and complicated. first with coin and then the programming haut not out. Anyway, the thing is no longer operational after a week. When the dog barks, sprayed nothing. The collar is perfectly applied and was hired by me several times.
