Transmitter muffs are wonderful invention Mick. I wouldn't fly in the winter without one.
They do take a little getting used to. Don't fly your favourite model until you've got used to the muff while flying a foamy,................just in case.
In very cold weather I've found that the viewing panel can mist up with condensation. I either ignore it or wipe it clear with my thumb.
I still wear a thin fleece type glove inside the muff in sub zero temps. The muff won't make your hands warm, it just stops the wind chill effect................ They're well worth the money. ( In my opinion.)

Go on Mick, treat yourself,......... you know you want to! :wink:
