Really neat little tester! I love the voltage display and the RCD test, which works.

However - it has a somewhat big flaw (for me, in Denmark):
In Denmark, live is on the left side, but this tester thinks it's on the right. Also, it's a Schuko plug, which means it doesn't connect the grounding. Easily fixed though, I made an extension cord with live and neutral reversed, and the correct grounding pin, and a Schuko female plug connecting to the tester. This way, it reads correctly and as a bonus, it's more comfortable to use, since I can plug the extension cord in the outlet, and hold the tester in my hand.

If you are prepared to mess around with it in case it doesn't work correctly with your country's wiring, I highly recommended it!
