dog collar

Have you tried using an innotek bark collar? We're looking for some reviews online so we could determine how good they are and if they are worth buying. I know it can be quite annoying when a dog barks too often, especially when you are sleeping. Incessant barking can annoy neighbors too! I guess bark collars are a great invention, if used in the right way. I wonder really how effective they are. I would appreciate your feedback on this product.
