This is the easiest-to-use storm cover I have ever come across. (This is my third baby and about the fifth pram or stroller I've owned). You don't need instructions or ten minutes fiddling about (while baby gets wet) to put it on. I like that it doesn't need straps, you just pop it over the pram and it holds in place. It didn't fog up or create a mini-glasshouse effect around my newborn. Well done on the design. Ps. LOVE my smart lux too!
