For me when i put the battery in it started up but then the red light blinked which the manual said was expected and i just popped it out and back in and it stopped blinking

Since my big baby is a yapper he definitely started barking at noises and the collar started going to work increasing the level 3 times then momentarily stops

I find it helpful to say no while the collar is doing its job just to make sure the message gets through

The only con about this collar is that it is plastic and plastic when scratched can be damaged

We have a terrier mix who barks a lot and this started to work within a few hours to correct the behavior

Its starting to work just based on the beeps and not even getting to the vibration stage

Only issue is that if i’m holding her close my voice will set it off and it will start beeping
