Bought on 11.11 and received in 2 weeks... fast. This plug-in power meter has the cETLus mark on it so it is built to safety standards acceptable in North America. Recommended! The quality is good. Plastic case is durable, and strong. The meter is accurate compared to the 4 other units I've tested (different vendors). Easy to use and view with large numbers. It didn't ship with a CR2032 coin cell, which purpose it seems is to allow viewing of stored data when unplugged. During disassembly, the battery was not left in place, no loss of data. Minor Improvements: MODE spelled MODEL. Requires better LCD contrast from UPWARD angle viewing. Downward contrast is super, but who views from FLOOR? Swapped red LED with white to try and backlight, but unsuccessful... needs backlight diffuser in LCD sandwich.
