Coffee Appreciation

Hello there! I'm a friendly Cubika owner! The plastic tamper is indeed only 55mm, and it's a pain in the arse when you're trying to get an even tamp, since it doesn't touch the sides. You're probably looking at a 57-58mm tamper, since most Gaggia portafilters are 58mm. I've been tempted by the ones here: http://www.espressoservices.co.uk/coffee_tamper.html

...but for some reason £25 on a tamper seems excessive when my espresso machine only cost £35.

I'll have the yellow handled one :-)
Tamp is important so I may spring for a non-plastic generic tamper meself one of these days.
