Checked insulation measurement with a Fluke 80K-40, basically OK. However, makes internal arcing noise in 2500 V setting (but not in 5000 V setting!). 14-day delivery, nice.
Pleasantly surprised at detailed 4-page instructions in proper English. The battery compartment was a little bit tight for standard AA batteries, but easily fixed with file in a few minutaes. Unbelievably great value for the modest price. Beautiful, bright, large color display, a pleasure to use. Buyer-friendly customs declaration.
