I tried Portal Reloaded about a year ago and got so confused that I shelved it for a while. After revisiting it, I don't understand why I got stuck...Perhaps I was not feeling up to the challenge because I had other things going on and gave up quickly.

Reloaded is a very unique fan-made experience, and the added challenge is quite welcome to people who have mastered the first two Portal games. Only one chamber ruined the experience a little, due to an annoyingly hidden mechanic, but other than that I think these puzzles are an amazing addition to Portal 2. Highly recommend it!
