Simple and sturdy!

The adjustment was pretty straightforward after tugging on the knots a little bit. I love how simple it is, but my favorite part about it is definitely the tag holder. The silencer is a nice touch but not having to ensue a battle with the thicker tag rings to get it on there is wonderful!

Simple collar

It's exactly as described -- a no-nonsense collar that's easily adjustable. Perfect for my dog when she's lounging around the house. For dogs who pull on leashes, invest Ina harness.

It's easy to use, easy to get on and off, and most of all my dog likes the lightweight feature and since it's skinny, doesn't bother her so much so she isn't scratching her neck all the time. I like it!

Great Collar

Love this collar and so does my Rufio! Got tired of being a part of the throwaway culture and purchased this collar because it's lack of plastic clip.It's very reflective and that is a life saver for camping and night hiking. Decided to get the matching leash as well.

Love it

Absolutely love the quality of this collar. We mainly use it as an ID collar for our husky, but when we do use a leash with it, we love having the loop located seperate from the tags.
