I saw the euroreef nano skimmer at MACNA 2 year ago and it was cool looking.
If you are talking about sapphire aquatics then it is a nice skimmer. All skimmers take about a week to break in. The owner of Sapphire is super nice and make beautiful acrylic equipment. They are located out of Houston so if you need any custom acrylic work I highly recommend them. If you have any issues with the sapphire I recommend contacting them.
