      Easy transaction, got exactly what was described, shipped out the door and into the mail quickly! Great communication getting the shipping combined, too. Also, got here *much* faster than expected: ordered 14DEC from China, arrived 24DEC to my door in USA, and I would have been fine with some time in January. Lets hear it for the folks working in the supply chain!
      Follow-up from: u***u- Feedback followed up by buyer.- Feedback followed up by buyer.
      Finally got around to using this, and it works great. It reads very closely to my multimeter, so it’s reasonably accurate. It also has an over-power protection that I must have missed in the howto’s online, a nice plus!
