I have also heard good things about mr cool.

I have trouble gauging them because they have flooded the DIY youtube crowd with free review units. There is no direct quid-pro-quo that I know of, but it's rare to see a DIY person bash something, and I worry it's out of a fear of biting the hand that gives them free stuff.

I bought mine, and this was before they were giving them to YouTubers. I've definitely seen those videos since then.
