I agree, I have a few LR atties on my TT and they don't seem any different, just run the battery down quicker.
I mistakenly bought some non tank mega attys, the ones with the 'wool' inside and they offer a lot more flavour than the tanks so I use these as home.
I just put an order in with flavourart in Italy. When you find a flavour you like you can bulk order it and get it really cheap. 250ml of apple pie and 100ml of RY4 flavouring (RY4 is a fair bit more, probably it's popularity) cost me just over £50 delivered - this is enough flavouring to make close to 2 liters of juice
- should keep me going a while.
