I got the 1.5” limited slip martingale Fi compatible collar for my pitty/great dane mix (main color blue, with maroon accent). First, it fits the Fi perfectly and the size was absolutely perfect for him. It’s definitely wide, so the 1.5” width is probably better on a bigger dog, but it was *exactly* what I wanted. I wasn’t able to find really any other Fi collars in that width, especially not anything that gorgeous. It. Looks. Fantastic. Combined with the brass/gold nameplate, he looks like a distinguished admiral and he constantly gets compliments and people asking where I found it. The gold accidents (d-ring and the other hardware- I’m obsessed with the rivets/screws (?) and how they add just the perfect amount of shine) pull everything together and add beautiful detail to the collar. Not gonna lie, the turnaround time was pretty intense, but I believe it was because of the nameplate which they stamp in small batches. The quality is also amazing, I always walk him on a harness because of how strong he is and how he pulls, but I had to hook his leash to the collar after his harness broke halfway through a hike, and it handled him with ease and no signs of strain at all. I absolutely can’t lower my rating because their customer service was so amazing and they were responsive and so nice even when I bothered them a couple times checking on my order. And I can honestly say that it’s worth it seeing how handsome my baby looks (he knows it!) and knowing that he’s safe and monitored with Fi at the same time. Thank you so much to SBDC and I promise you won’t be disappointed by either the appearance or quality at all.
