User Manual Delonghi EDG250.B Nescafé Dolce Gusto Jovia Pod Capsule Coffee Machine

In the UK it has 3 pins. I received with 3 pins, I am from UK

This is a much better quality coffee machine as you said.
The Tassimo's automatic function is good however I
personally prefer the Dolce Gusto and have one myself.
This model is normally £80 so you would be getting a very
good coffee machine for your money.

No the design is for dolce gusto pods only

Yes. The tray height can be adjusted to take all cup/ mug
sizes
