Rusted grommets after a month

I absolutely loved the customization, ability to easily clean, & FI collar integration, and really had high hopes, but I'm so disappointed. I purchased on 03/17/2025, received my order about 10 days later, so my pup has been using her new collar less than a month and the grommets have already started rusting. We live in Florida, and she has an active beach bum lifestyle, so I went with a bio thane collar, but apparently the salt water was too much for the grommets to handle, which is so frustrating to pay so much money on something we're not going to get much use out of.

Birthday Collars

I got two collars for two dogs I am close with and have the opportunity to see grow. They both have their liquid fun. The black one loves snow and the yellow loves to dash through water. Both are sweet boys and their birthdays had passed but got them a few days after the yellow ones birthday. I will be ordering one for my girl once the time comes!!!!

What great birthday gifts for two sweet pups! Thank you Gina for sharing their pictures as well :) We love seeing your new gear in action!
