Great precision, minor config learning curve

The weighing accuracy is impressive for the price point. It took a little time to configure the APN settings for our specific carrier, but once done, it works perfectly.

Solid performance

Good value for money. The 6-digit display provides clear readings. The only reason for 4 stars is that the antenna cable could be slightly longer for some installations.

Robust industrial build

Used this in a dusty warehouse environment. The IP65 rating holds up well, and the LED display is bright enough to read from a distance. Highly recommended for industrial use.
