I called Nintendo last week and spoke to the manager. I asked him why some places are giving 2 years warranty and some only 1.
According to him all HK stock only has 1 year warranty by Nintendo. However, Prowell is a dealer in Shum Shui Po and they are offering an additional 1 year warranty on their own for their stock. So the repair for the 2nd year will be taken care by them. So if any problem on the 2nd year you have to deal with Prowell and there is no guarantee if the repair will be free as conditions apply.
I went ahead and got the extended warranty coverage from Fortress for $350 which gives my switch an additional 2 years warranty (Total 3 years). This way, any problems I face in second or third year, I can take the console to Nintendo and have them repair the problem officially and then I pay for them and then claim it back from Fortress. This will be safer since official parts will be used for repair.
Tablets are delicate and with alot of gaming the LCD or battery can be overheated by use so best to have more than 1 year warranty.
This is the most expensive game console of all time, with all this puzzle like accessories ,it seems only a few hundred per piece but you end up spending few thousand only on those over priced peripherals
