Shuaikang, Haier and Midea, which electric water heater is better in electricity protection?

Confucian classics and history do not represent technology. At present, Haier's strong discharge technology is recognized as the best in the world, and Haier's technical specification for discharge wall is also the national standard used in China. I believe that technology chooses Haier's discharge wall. Of course, the price is much more expensive, and Haier is the first choice for safety reasons.
