This may well be a case where the Chinese told their customer the device has temperature compensation and the Amazon vendor never bothered to check it out before advertising it on eBay. Temperature compensation intergral to a regulation device is stoopid engineering. The regulation device heats up while controlling voltage and Marx Bros seizes control of the entire act. Integral temperature compensation -can- be done but no one on the face of the earth is going to build a device large enough to keep temp increase under <1c then do a compensatory adjustment to account for the +1c. Another GINZU knife marketing con.
