Quite different in this patent!
Here one gets with each x-arbitrary plug just prior to use of the can to protect out! You put the respective power plug in the protection, turning it slightly to the narrowing notches and then pulls it out!
Certainly you have to then as long as you use the can to protect long lie down somewhere but I do not see as a minus point because it must be removed within seconds from the can and use!
Especially but the can is fully protected, even against splash! This is especially helpful if there is no splash-proof sockets are available in kitchens or bathrooms!
CONCLUSION: Simply only recommendable !!!! Best protection for small money! Quick and easy inserting and removing! Fit also perfectly !!!
