So... I bought the wrong Fi generation. The collar didn't fit and I had them etch my dogs name and details into it. It looked great! Just didn't fit the Fi device. I reached out to them and let them know the situation. While they couldn't offer me a return/swap for the customized collar they did help me with the purchase of the right collar. The service was quick and instead of leaving me dead in the water they met me in the middle. Cannot expect any more than that from a good business. Thanks you!
