It is incredibly easy to use. The zipper quiz works well to tell you what you need. Both the regular zipper in the universal adapter work very well as advertised. Incredibly happy with this purchase!
Fits really well with my TNA Parker. I'm currently using the extension and gradually will switch to the actual piece. I can't wait to use it next winter with my baby. The quality is also durable. It stays put.
It has made our getting ready to go outside in the cold fast and easy. The only thing I find it difficult is to get the first teeth in the sliders especially with a baby blocking my sight. Beside that I am happy with my purchase!
Very easy to transfer between coats which I like as our Canadian winters have a wide range of temperatures and conditions.
I was excited to purchase the universal adaptor - it was pricey but allowed me to use on various winter/fall jackets. It does slide a bit as some of the reviews said but that wasn't a big deal for me. I was really disappointed and sad however, that the plastic broke while I was removing it from a jacket. I wasn't pulling that hard and used it for only 2 months.. expected it to last longer and be sturdier considering how much it was.
