I like the 901 atomiser much more than the Classic - but prefer the Classic mouthpiece & bigger carts... The 901 carts don't last 2 minutes without needing filling or topping off.
Here is my solution - cost=free, result=superb!
Tools:
Hacksaw, dead Classic atomiser & a 901 atomiser.
Remove the gubbins out of the end & cut 1cm off the end of the Classic tube.
Keep the rubber seal/ring (This was a generic Classic atomiser - not a Janty)...
Cut the outer tubing of the 901 to just below the level of the wirewool - carefully!
Push the rubber seal/tube over the 901 until it is almost on all the way.
Put a Cart in one end of the tube and twist the 901 in the other end, until you can feel the Cart just being pushed back out. Adjust by pushing the Cart back in until flush. The rubber seal keeps it secure & air-tight. The hole in the 901 is/should be visible.
Screwed on to the Screwdriver...
If the 901 atomiser goes to atomiser heaven, just cut down another one and replace.
It works great. Bigger cart, best atomiser & long battery life and power.

Of course you don't need the Screwdriver because it will screw onto the 901 battery - but the SD makes a difference.
