Fantastic Product, Great Company! These tubes are great for a number of projects concerning thermal energy, and Dakota Lithium has priced them well for the home experimenter. They’re not kidding when they say they can get them to you safely. Fantastic solar evacuated tubes. Solid construction, excellent packaging, and they work!
