FONPOO Bark Collar Shock Collar for Dogs Training Collars 7 Sensitivity Adjustable Level with Humane Shock Warning Sound for Small Medium Large Dog

I put the battery in this and turned the sensitivity up as high as it would go and my dog was wearing it and barking loudly and nothing happened. The device would beep if you changed the sensitivity so it wasn't that the battery wasn't working. It just didn't work for me. That being said if you are willing to give it a try the design is really nice and light and sat well on my dog who is about 50lbs- I would say it would be too large if you had a dog under 20lbs

Not sensitive enough. does not work with dog bark. I can get it to beep if I shout at it. Will try to return it..FONPOO FP665V Dog No Bark Collar for Bark Control with Harmless Warning Sound and VIBRATION 7 Levels of Adjustable Sensitivity Control Electric Anti Bark Collar for 12-120 lbs small and Medium Dogs

not the highest quality but I wasn't looking to spend much. My Shepherd has a very thick coat so I think he just can't feel the vibrations. It might be better for a small dog with short hair.

Got this on Friday, battery dead on Tuesday. Dod did not wear it at night or during the business hours, so its not like it got overused.

very unhappy my dogs bark more now with them on

My dog was with very serious barking issue,it works to keep my neighbors from complaining.This is a very effective bark control vibration collar. it with different settings for the 7 sensitivity level of vibration and correction and it makes a sound first that helps stop her from barking. I've tried a lot of bark collars and I can say this collar is by far the best out there.Definitely happy with this product and would highly recommend it.

wouldn't work when our dogs barked.

Great collar. Easy to set up. Fits snug and perfect.it is working great so far and my dog has picked up pretty fast not to bark at everyone.
