Some online group purchases have Philips razors, but they are all European versions and there is no national warranty. They are responsible for maintenance, and I don't know if it is reliable.

Not reliable! No matter the European version or the American version, as long as it is a formal channel, you can enjoy the global warranty provided by Philips!

Although it doesn't matter whether Philips razors enjoy the global warranty, what matters is whether the merchants can provide them.

The global warranty provided by merchants should be genuine, and the biggest problem that merchants can't provide is that they may sell you high imitation fakes. The reason why they only provide merchant warranty is just to give you psychological comfort. This is like a shopping receipt.

Please be careful to buy those that can't provide global warranty. You have been fooled too much.
