Unfortunately they didn't work for me at all for they doesn't work with soft tissue. My skin tissue is too soft and it won't stay in place. So be careful unfortunately it won't work for everyone. The firmer your skin is the better it may work.

Now we are living a bark free life! Within two days it had cut out 99% of non-essential barking! At last you can feel peace and quietness in our house! We love our beagles but they were driving us crazy! It really detects barking from far away, now we don't even hear our neighbor dogs. Great quality and cute btw...This has been a life saver! We are able to get proper sleep now!

I like this tracker's appearance so much. It's so light and thin. All functions meet what i expected. I have to say one function that surprised me. Message reminder is so practical for me bc i always put my phone on silent mode, which made me miss a lot of messages. Now this tracker has resolved this problem perfectly.
