It works perfectly, my girlfriend has a very annoying dog, with this I was finally able to push her away without physical contact, it bothers them quite a lot (like she bothers me) just activate it to move away, without being rude or aggressive, they simply leave because of the annoyance, I wish there was something like that for the annoying 😜 relatives
It also includes black light to visualize stains and dirt on beds and clothes in general, excellent acquisition 👌🏽

worth the price, awesome product, nice thank you

I received it on time, it is of good quality and I am very satisfied with my purchase Thank you!
