Customer Reviews
Obsessed with the new collar for my puppy. The quality is great, and I’m excited to have a collar that’s easy to clean. Love all the color options and will likely get more in the future.
Thank you Alyssa! Your pup is adorable!
Our ‘land seal’ loves to get stinky in everything—mud, pond/lake/stream/ocean/brackish water, washed ashore critters, more mud #mudfordays. Our Fi Series 3 BioThane Collar has been a life saver. No more stinky, wet collar that used to not only get disgusting, but that would end up giving him neck rashes/irritations. The Fi Series 3 BioThane Collar wipes right down and still looks as bright and shiney as the day we got it. Thanks HTH!
Oh my! Your 'land seal' sounds adventurous! So glad the Fi Collar is working so well for you (Both!), Thank you Liz!
