Great ..wish the water reservoir was a little larger though … and you have to work quickly else the water cools down..also care must be taken not to overfill it as it will spill out as you put it together and you could burn your hand.. Its very convenient..I will take it wherever i stay where my hosts do not drink coffee.. .well they do..instant coffee .. which i hate! I tried it with the adapter as well and found my Nepresso COMPATIBLE capsules would not puncture .. so need to use Branded ones. Overall, its worth the spend.. just requires hot flasked water and finely ground coffee or capsules if you have the adaptor. A bit of effort needed to pump but so worth it!
