How hot is it? I've been using UP regulators and have different experience for different models. The valves of 099 really suck (with audible humming sound) and the transformers are hot. 3 of them died for less than 6 months. The valve of A151 is great. It's totally silent (which I think a branded and decent valve should be), and not hot at all. I've been using it for over 6 months without any hiccup. To avoid any problems, Airtec Valve is a good brand to recommend.
