The device updates the position every minute. It's very easy to program but I did it in about 40 minutes with patience. The good quality necklace, real leather. My cat weighs 8 kgs and it looked great in size.
It arrived super fast, the staff is very attentive and helpful. Well-packed, and the product is exactly as described, the collar is long and comes with enough holes for small pet as well as large ones. Loved it, Thank you
It came quickly. Everything works. It is a pity that there is no instruction in Russian language, but the YouTube is full of reviews so I set everything up in five minutes.
