We love the storm, shield and storm box set up. It has turned our GSD into a year round vehicle and we can bicycle with our kiddos in just about any weather. We will frequently bike them to school and 10° weather and they say that they are toasty warm in the back. We also use it in the summertime and keep the sides up, which keeps them nicely shaded, and the sun off their face faces. It has worked great for our family and has held up well for about four years.
The product is superb, but I wish Tern would have give me warning about the substantial import taxes that this would incurr. If I would have known, I would have bought from a local supplier
