Great concept but its a hassel to use.
I fell in love with the idea of not having to struggle with a blanket or to wrap my son up in tons of layers before leaving the house. The biggest problem I had with the product was that I had a hard time getting it to fit my Britax carseat. Each time I have to leave the house its a struggle getting the car seat cover to fit. The corners would slip off and by the time I'm done it takes an extra 5-6 mins before we can leave the house. I probably won't buy this product again.
