This particular brand really works well for my 100+lbs pooch. He’s never exhibited any adverse reactions. The only time I found a tick was when he lost the collar and was boarded with his sitter who lives in a wooded area. My only complaint is that the collar doesn’t always stay secured using the notches…2 have been lost while out walking.

I have to wait few months to know how effective it is. I bought the prior one from the veterinary store. This one was very effective for my dog, didn't have any problem. Current ebay product looks similar even that the box didn't bring the 3 reflective collar items that the product I got from the veterinary store. The information found on the rear box has a different background color. Ebay is darker (see pictures). I am not sure how genuine and effective this product would be. Price is very different. The product from the veterinary store cost three time more. I would get back within few months for follow up.

It does exactly what it says it will do. My dog doesn't have a single flea thanks to this collar. I love it and is well worth the money.

These flea and tick collars are great. I have to big dogs and I live in the woods. I have used these flea collars for years. You change them every 8 months. I have never seen a flea or a tick and they are a small price to pay compared to the monthly treatments.
