I have a G20 and enjoy it greatly. I've gone one step further to try to keep warm lather warm to the end of the shave. At the local Goodwill store (charity shop, second hand store) I found a small hot plate, about 4 1/2 inches across. Probably was used to keep a cup of coffee or tea warm or to warm a bowl of aromatic herbs, etc. When I start my shower I turn the plate on, load the G20 with the hottest tap water I can get, fill the bowl and soak my brush till done with shower, ready to start a shave.
