I was looking to upgrade my dogs’ original Fi collars and boy did I. They’re beautiful and turned out exactly like I imagined. Also super durable and easy to clean-both requirements for my high energy/maximum chaos mixed breeds. Highly recommend!
Thank you for taking the time to leave a review! We are thrilled to hear that our Fi Series 3 BioThane Collar exceeded your expectations. We strive to provide both durability and style for our furry friends. It's great to know that your dogs are loving their upgraded collars. Thank you for recommending us to others. Happy adventures!
Absolutely beautiful and sturdy. 10/10 recommend.
Thank you so much Olivia! (Thanks for the pic too!)
This is the best fi holder collar. We love the colors, the fit, and it’s relatively soundless as far as fi link clinking goes. Tobey gets so excited when I get this collar out because it means ADVENTURES!
Thank you Erin, and Tobey! We are so glad you are loving your new Fi Collar! *thank you for sharing pics too, we love pics!
This Fi collar is very nice. The Fi fits very close to the collar without any space. I have used other Fi compatible collars where the Fi kind of hangs away from the collar. Looks great too!
So glad you are happy with our designs! Thank you Christine!
We are very happy with this collar as our dog no longer has signs of irritation and the brass hardware is easy to use! It also looks great! Thank you!
Thank you so much, Cynthia! 💛 We’re so happy to hear you’re loving your new BioThane collar—and especially glad your pup is more comfortable wearing it! 🐾
It’s wonderful to know the brass hardware is easy for you to use and that the collar looks great, too. Comfortable, functional, and stylish is always a win! Thank you for choosing High Tail Hikes, and we hope you and your pup enjoy many happy adventures together! ✨
I was looking for a good replacement collar for the Fi tracker and this is it. Great color options and very comfortable and durable for my pup.
Thank you so much, Robert! 💛 We’re so happy to hear our Fi-compatible collar was exactly what you were looking for. It’s wonderful to know your pup is enjoying a collar that’s both comfortable and durable, and we’re glad you found a color you love too!
Thank you for your support, and we wish you and your pup many happy adventures together! 🐾✨
Excellent quality and uniquely durable
Thank you Robert! So glad you are enjoying your new gear!
The color is beautiful but it’s not a very good fi collar. The layered design makes the tracking inaccurate, which i didn’t know that it would do. I would’ve chosen the integrated design had I known. It has thrown off the fi collar from tracking mg dog’s eating and drinking habits. Also part where you place the tracking device is very uneven so it causes the device to sit weirdly and it bunches up the collar slightly so it is very clunky. The strap keeper is also very useless so I do not recommend getting that as an add-on as it installed between the two brass fixtures, where the d-ring is. It is installed the same exact spot in the d-ring so it serves no purpose and the tail of my dog’s collar just dangles.
Hi Jessica, thank you for sharing your detailed feedback. We're sorry to hear the collar didn't meet your expectations and will pass your comments to our team for improvement. If you'd like assistance with a different style or a return, please reach out to us directly. We appreciate your input and hope to serve you better in the future.Hi Jessica,
Thank you for taking the time to share your feedback. I'm sorry to hear the collar wasn't the right fit for you and your dog.
Our Layered Fi collars are designed for customers who prefer not to have the tracking unit directly against their dog's neck. We haven't found that the Layered design affects Fi tracking accuracy, eating, or drinking data, but we will pass this feedback on to the makers of the device.
Regarding the strap keeper, it is designed to allow the strap to lay flatter against the collar after it passes through the buckle. We are not able to place it lower down on the collar as there would be nothing to hold it in place. We understand if it did not meet your expectations.
We appreciate your feedback, as it helps other customers choose the design that best fits their preferences and their dog's needs. If you would like to return your collar, please reach out to us at support@hightailhikes.com and we'd be happy to help with this.
Amazing collar, can’t wait to order another!
Thank you so much, Elizabeth! We’re so glad you’re loving your collar — that means a lot to us. 💛 We can’t wait to make your next one! 🐾✨
Waterproof, easily cleaned, I love this collar!
Thank you so much, Melissa! We’re so glad you’re loving the collar — waterproof and easy to clean are two of our favorite features too. We appreciate your support and hope you and your pup enjoy it for many adventures to come!
Love this collar. High quality, looks even better in person.
Thank you so much Brittany!
I absolutely love the collar. I've been a dog groomer for over forty years and I've seen a lot of collars. This collar is bright and colorful, strong and washable! It's perfect for my active Russell Terriers.
aw, Thank you Joanne! So glad you're loving your new gear!
This collar is well made, looks good, and fits great. The color options are nice. The Fi connections are solid, and I really like the layered design for removing the Fi unit for charging. This is second collar we’ve purchased from High Tail Hikes as our pup has grown. I’m sure it won’t be the last.
Thank you James! We are pretty proud of the Fi capable collars! We appreciate you :)
