PAWONIT Citronella Bark Collar for Dogs,Dog Spray Bark Collar No Shock Anti Bark Collar Humane and Safe Citronella Bark Collar for Small Medium and Large Dogs Rechargeable

Didnt expect much but this tiny vaccum is stronger than some bigger ones i had very compact and gets the job done.

I keep this in my desk for quick clean ups of eraser dust to glitter fallout, etc. No issue with battery life, maintains charge for a long time. Glad I bought it.

Shipping was quick but when I received the item, it doesn't work even after I charged it. Returned the item!

Good for the car and picking hair in the bathroom.

I was very pleased with how this spray bark collar functioned for the first 6 months. It allows a dog to bark once without any response, but with two or more consecutive barks the dog gets an instant response of spray. My dog learned very quickly that one bark was OK, which I didn't mind, and I actually think it helps prevent a dog from getting too anxious without being able to bark.However, after 6 months of use I noticed that the collar was not consistently working, and my dog began figuring that out as well. In the last few weeks it became evident that it was no longer working at all. Changing sensitivity level did not matter. The unit no longer picks up the bark (noise or vibration) and has become a useless piece of jewelry.
