I'm really pleased with it so far, the MC2 has a really good quality feel to it and is well made. The grind adjustment is in very small steps so it gives you great control but is not easy to switch between different grinds.
You can get from most cheap poundland type shops clamps like these - but you need the ones that are about 5" long instead. One of these on the knob *fnar!* and easy adjustment is yours.

I've only had 1 disaster so far which I
think is down to either too coarse a grind or not tamping with enough pressure - I started to pour my shot and after a few seconds the machine decided to spray the coffee sideways out of the machine all along our kitchen wall and even hitting the curtains! I managed to laugh it off but the wife was not impressed
I'm guessing this happened because there was not enough pressure to hold the flow back and make it drip through slowly? Does anyone have any tips on this? I haven't done it since but I do find it a bit of a guess every time I tamp! Is it better to go to hard rather than not enough?
Do you have a plastic thing underneath the basket in the portafilter? If so, thats the cause. In order to get it working properly, you'll need a new filter basket to sort it. There's lots of info on it online - it's a crema enhancer... and it sucks.
If not... I'll have a think.
As for tamping pressure, do you have a set of bathroom scales? If you do, tamp on that and tamp to 30lbs or 13.5 kg of force. Yes it's a lot, but it's a good value.
