How to identify the authenticity of Philips electric toothbrushes: 1. Look at the packaging, which is consistent with the pictures on the official website, and the packaging is exquisite, well-printed, and has anti-counterfeiting stickers. 2. Recognize the trademark. Counterfeit goods generally have different trademarks and are just a side effect. 3. First go to a large shopping mall to look at the model and take a photo, then go to a small store to compare prices. Another way is to go to Philips' official website to check. This is safer, and this is probably the way.
