I've had the nano skimmer for a little over a year and it gets the job done. Had an issue where it kept overflowing. Turns out that the inner piece of the body was clogged up. Cleaned it up and it went back to normal. My only other complaint is that the magnet could stand to be a little stronger. The skimmer has a tendency to slide a little when in certain positions. It's possible that they might have fixed that. I could probably alleviate the problem by putting something under the magnet to provide some friction.
