I have my Caravel for some two weeks so I thought I'd post my first impressions...
The very first impression was not that great... I was happy my machine arrived but it turned out it has three-bolt plug (basically the seller was a bit misleading when he replied to my question about it, anyway he claimed it can be easily changed) and it smelled a bit metallicaly. But then the whole idea of the machine is just wonderful. It took my heart completely.
I cleaned the boiler with a metal grate and washed it etc and it turned out the water tastes good. After couple of shots I can say that the espresso is very good. It's amazing that I can produce half-crema (after shot settled) in the glass without any effort nor lever-experience
I have the same grind as for Vivaldi, put almost 11g of coffee in the basket, level with a bit of compressing and tamp with my thumb and then I pull. I never ever thought it could be that easy. Shots resemble Vivaldi's singles yet they have clearer taste.
Yesterday I removed the plastic dirty legs. I still have to change the cord (dirty too) and the plug and then only hand grinder is what I need to have coffee happiness at work.
