I consider the GWG-100-1A3 to be exactly the Mudmaster that an ordinary buyer deserves. The maximum protected case and buttons, no problem second hand, solar power, radio synchronization and steep backlighting – a vivid example of how the Japanese know how to work on errors. The lack of sensors of someone can pose a deadlock, because we are dealing with a representative of the ruler Master Of G, where they should be by definition. On the other hand, the manufacturer has set itself the goal of finding a compromise solution – either sensors or a solar radiator. Do you want both? Then take the GWG-1000, but be prepared to shell out almost twice as much blood.
