Bests & Worsts Reviews from Amazon

So far I’m amazed with this product! The day after putting the collar on my dog and cat there were no fleas to be found!! We’ve had them on for about 2 months now and I still have yet to find any fleas! They were previously covered in them and I couldn’t find a product that would make them stay gone until now! My sister in law has now purchased some as well and has had the same results!
