I use for my dog a reminder necklace Canicom 200, which allows to not let him go, and protect itself against bad ideas and kind of follow a trail in the forest at night. The problem is that just the night it was hard to locate in the park where I walk it. With this necklace more problem, I locates all the time and it does not look too ridiculous. there are several settings to blink faster or slower the collar or not at all (which I prefer). I used two to three times a week (20 minutes on average) for three months and the battery is still ok. he also took slightly water, hair of very wet dog and again no problem. So at this price (4.50) do not hesitate. Perfect for city walks at night.
