The reference fulfills exactly what is promised. In the original reference my son was always wet with sweat on head. Since we have the summer cover, this is no longer occurred. And that in the heat of around 30 degrees. The cover feels at first attempt much more enjoyable as the original reference, just for the bare legs and arms, when it's so hot. So with regard to the benefits, great thing, really recommendable without not the point. I'll probably leave the reference even in winter it. Too bad that the attachment is so difficult. Unfortunately, there are no reasonable guide to. Compliance I spent a whole evening so to tinker the summer terms. But even with instructions, it would be tricky - that's just in this baby carrier. Since even this reference is so hard to install and fit well be true flat and even, I would absolutely recommend to buy the original accessory of Romans and not some universal reference. I can hardly imagine that this could fit neatly.
