Been using it pretty heavily for over a week and the collar is still stiffer than I'd expect it to be. I'm sure it'll break-in, but the 'martingale action' is a bit rough for now. As an engineer, the top and bottom edges of the 'u-cutout' on the leash clasp aren't rounded and neither are the edges on the collar 'd-dring' so the anodizing along those edges doesn't hold up. With some strategically rounded edges the coatings would have stood up to abuse longer, maybe anodizing thickness could be increased too.
Regardless, I'm satisfied, it's a good looking combo and it's otherwise very well made.
My first martingale collar and I love it. It’s put on and off quickly and it looks great on the dogs. Also I’m a big fan of the frog clip.
Geddy loves all his tuenne gear!! Its great on hikes, for travel, and looks great!
