First of all, I want to mention that BULL is the largest manufacturer of Extension board & is the leading brand in USA, Germany, France , United Kingdon & Japan. Pros: + It’s made of high quality Polycarbonate Plastic ensuring strength & High-temperature resistant. + It has integrated pure brass circuit ensures high conductivity. It’s the World’s first of its kind. No wiring inside (as found in other brands) + 100% pure brass bar inside fixture reduces risk of short-circuit to minimum. + It has three-core wiring of plug outside. + It works with all international plug types. Different standard of plugs can be used. + No loose plugs due to international sockets with “Lock-in” technology. + 4 international sockets with individual silver contact switches for lifelong usage & individual LED indicators also.
Cons: - This does not have a circuit breaker (or fuse) for overload protection. ============================================================ Last but not least, BULL uses the most specialized material and technology to provide customers with a safe and comfortable environment for using electricity, thus improving life quality.
