Tickless Pet Ultrasonic Anti Tick Bite and Flea Spread Device Orange | Fragrance-Free Protection for Cats and Dogs Lasts 6 Months | On Collar and Harness

Seems to work so far. It's hard to tell because it doesn't light up or make any sound (that I can hear). I use Frontline on my dog to kill the ticks, but I wanted something that would repel them as well. My dog is large and solid white, easy to spot ticks before they bite. I've attached the unit to to her collar and I put her collar on her only when she goes outside. I have not seen any ticks on her except for when she went out without her collar, then, sure enough, she came in with ticks crawling on her. So I have to believe the device is working. Note: We do not have fleas where we live, so I can not comment on the effectiveness on fleas.

Waste of money, did not do anything that it claimed to do!!!

I have a Australian Cattle Dog (Blue Heeler). She is into the weeds and woods constantly as she runs outside. I put this on her collar and without any other flea and tick applications - we have not had any issues with ticks or fleas. Says it is good for 6 months and ours is still functioning after 8 months. Highly recommend.

Very pleased with this item! I will order again when the time comes! My people are still using chemicals to treat flea and ticks I don't understand. My neighbors always ask what is your dog wearing? And I have not yet to see any of them purchase one for their pet. So happy I don't have to give my puppies chemicals!

After a really difficult summer with lots of ticks this product worked really well. Our beagle wore this outside everyday. We only noticed a few ticks over the past few weeks in comparison to her bringing them in the house nearly everytime she went outside. There's no smell which was a bonus. Our dog hated the scent of sprays, making them almost impossible to apply so this was an excellent alternative.

I couldn't tell that these electronic collar fobs did anything. I put them on 3 dogs & fleas were still a problem

Awesome product. No ticks since wearing it. Easy to put on the collar.

I took a chance and was disappointed. Used this on a Golden Retriever, no difference, does not repel fleas. All stages of flea's found in the fur. I can not say if it works against ticks. For those that say it works, I really hope so. But for me this is a big no. I gave it plenty of time. I am in the LA airport coastal area, not that that makes a difference.
