One small note about the Davide Mini (not sure if it applies to the full-size Davide as I don't have one) - there are 3 'relatively' small fill-holes. I'm able to fill using a dropper bottle without a problem - 98% of the time; but I'm very patient and forgiving
.
Using a needle-tip bottle (or one with a tip like the picture below) would be easier.
