Η Nintendo now offers free repairs to defective Joy-Cons across Europe, regardless of warranty status.
On a support page on Nintendo's UK website, the company says it will repair existing Joy-Cons for free problem even from normal use, in the United Kingdom, in Switzerland and in all the countries of the European Union, i.e. in Greece and in Cyprus.
It's not unusual as Nintendo has offered free repairs for out-of-warranty Joy-Cons in North America, Latin America and France, so it's just now extended its policy to the countries mentioned above.
However, there are some subtleties letterthe. As Nintendo says it may "refuse to provide repairs" for stick slippage caused by third-party accessories if it was caused by accidental damage, or if the controller has been "opened, modified or repaired" by anyone not authorized by Nintendo .
It says this offer is only available "until further notice," so it probably won't be around forever.
