Am disappointed've already bought many Scalibor collars, and was always enthusiastic, neither fleas, ticks or other still nichtsnützende critters are gone to my dog, but it was different with this collar. Unfortunately, it was indeed packed original and well preserved for a long time, but when I unpacked the collar it felt kinda old and porous, so was the effect, namely zero, he had ticks, as well as be captured somewhere fleas : (((
