Works as advertised. Clear "error" codes listed on the top of the tester. The GFI test button isn't like a simple button on a TV clicker, you gotta push it with a little force, but I didn't think it was bad at all. Would definitely buy again.

I was considering buying this conditioner because it came up when I searched for organic products; however, this line is NOT organic. In their ingredient list, Methylchloroisothiazolinone appears. This is a widely-used preservative in products and is a known human immune system toxicant. It is restricted in other countries production lines. Check it out at cosmeticsdatabase.com. Always make sure the ingredients are safe before you buy.

Super bright, batteries last a very long time. Very durable. I plan to order another on for my Boy Scout son.
