Rated 2 out of 5 by 5 reviewers.
Rated 1 out of 5by Questionable Ordered 2, one didn't have the clasp in the box. I haven't seen results from the collar, and I stretched it as the instructions say to do to activate it. Not a believer in the flea collars right now. 06/25/2016
Rated 1 out of 5by Not Worth The MoneyI bought two collars for my cats, one each. I also bought the spot stuff for my puppy, and NONE of it worked. Now my one cat is losing her fur because of a bad reaction to the fleas and my dog has a rash because hes allergic to them. The fleas are not jumping and biting and anyone in the house so I know my house is not infested. I'm really displeased that I wasted my money on this product. 10/23/2012
Rated 1 out of 5by THis product is awfulI bought this prodcut and my cat is still itching like crazy. This doesnt work. 08/21/2011
Rated 1 out of 5by Waste of moneyI tried Hartz spot on and the Hartz flea collar for more than 1 week now and nothing happened. Treated the house as well. My inside cats are still covered with fleas. 06/06/2011
Rated 5 out of 5by A flea collar used with flea meds will solve your problem!In the past few years, I have tried and tried to rid my indoor cats of the fleas that they picked up from the previous place that we lived and I found the right formula! NO single flea killing medication will kill them all! I bathed my cats with blue Dawn dish detergent (and you can only use the blue-and this is EXACTLY what the Humane Society uses upon intake of new Dawn!) and I purchased borax. The Dawn killed the adult fleas but did nothing to the eggs and larvae! The borax took care of the eggs and larvae on my cat and I purchased Frontline Plus for cats after trying ALL of them! I used these flea collars and cracked the code to getting rid of ALL of the fleas!! FINALLY! Each of these listed previously are all equally inportant! These flea collars ARE necessary! I also love the reflecting quality as one of my cats occasionally escapes so a car could see her at night if she were in the street. These are the BEST and they are very affordable!! 02/19/2011
