It has been 3 years since I mounted / dismounted every winter and I can not do without me. I use it on a DS300i scoot.
Easy to mount / dismount when we understand the trick (15 min max). You have to have plastic clamps (4) to properly attach the handles on-the rest is childish.
The outer flaps are very well designed so that water does not invade inside when the scoot sleeps outside in the rain.
The fleece lining is very very effective and the sleeves are completely sealed, even the flexible part of the thumb can actuate the handlebar.
The color does not move after 3 winters.
The only downside is the protection against theft, I paid the price !!
Sleeves + high bubble + apron + good gloves and plate winter tires (Metzeller Wintec) allow me to ride all winter except in the snow! (Brussels).
I hope my review will help you in your choice.
