Simple design. Good battery life. And so far it has been quite reliable. And at $30.00 totally fair. If you have been dying to drop your small torch and vapor straw we definitely suggest you stop by the shop and check these out.
Been testing out The Terpometer temp indicating tool this past month. I truly enjoy the simplicity. Though not perfect it has been giving completely reliable temps since the first turn on. Stop on in the shop to get a hands-on demo.
