After reading all the instructions on what to do and cleaning everything. It was very easy to do. I'm not going to lie I was nervous thinking I was going to mess things up but nope. I did a pretty good job. I like the cleaning process too. This was my first time ever making an espresso and I'm excited to make more. I wasn't able to try to make coffee from my phone yet because I couldn't download the app until I free up storage on my phone but it seems simple to work on there also. Oh yeah they also have QR codes you could scan to get help. That was pretty cool.
