For the third time bought Have a burning chair product and was disappointed for the third time. Problem: The switch! Off can be just fine only switch works only when 3rd. 4 Attempt. The devices get all short current at power then nothing happens. The whole thing must you then so long to repeat the current flows constantly. Extremely good for external hard drives if they are constantly short Get power surges.
Conclusion for me: Never again burning chair. Although "Made in Germany" stands on it.
