Firstly, it's worth bearing in mind that this is a quiet compressor for less than _100. Of course it's cheap and cheerful; the similar 9L Machine Mart quiet compressor is over three times this price.The first one I ordered arrived damaged, coming from Belgium via UPS, but the replacement was fine. As the other reviewer, I measured it at around 60db, higher than advertised, but compared to many standard compressors which run very loudly around 100-110db, this is still a very quiet compressor. Perfect for a small home workshop where space and noise may be an issue. It's far from the noisiest thing in my workshop.Upon first using it, I found the quick coupling euro-connector valve was stuck shut. After taking it apart, I found that it was just jammed up with metal dust from inside the tank. I gave it a clean and it works fine now. Other than that, no issues and no leaks. I only use it every so often, so I'm not giving it hard daily use, but it works as it should. I've so far used it with an airline, and nailgun, without problems.
