Diffuser, I almost fell to the floor when I read it. I must say, it is a superb innovation. Getting the idea is different and showing it in practice is great. My high appreciations for you.
The other day, I was riding in rains and constantly wiping the visor with my hands with little effect and I was thinking wish we had wipers for visors.
Now, it is time for me to put it in practice. I have a spare wiper at home.
