Very practical in that I can plug in different sockets even though they have adapters.
Unusable for two reasons: (1) Firstly, the two power switches are extremely sensitive to touch, so much so that even a very light touch on the contacts interrupts the flow of current. Absolutely useless for any application such as connecting hard disks, computers or safety-relevant devices. The switches are no comparison to the usual high-quality Steffen products. (2) Secondly, nowhere in the product description - neither at Migros nor on the Steffen homepage - is it clear that the two switches are apparently not intended as on/off switches but presumably safety switches that simply switch off in the event of overheating. However, this is again just a guess, as there is no usable description as described.
