the adapter itself is interpreted by the processing Perfectly and quite stable even He has to draw even from retentive sockets on the output side a lead which should also make it possible to plug, the contacts are all good and tight fit well there are no projections or similar to the contacts, the rest of the plug of a very hard yet flexible plastic the only drawback I see is that it is designed for 250V and 10A which means that you "only" 2500 watts can be directed through the adapter in the long term, I would here a 20A or 32A version very much welcome the 10 cents more in the production also are not the problem ...
Positive
+ Very good processing (very good recessed contacts without edges and hooks)
+ A "boss" for easy removal of the plug even when retentive outlets
+ The sturdy design
+ Good plastic (of not too hard or too soft)
Negative
- Limited power to 2500 watts (if you were the little extra cost considering a stronger version desirable)
In short
you will be buying a solid adapter loose his 10 years of doing if you're not overloaded him his service
