Bests & Worsts Reviews from Amazon

I made sure to order ones shipped and sold by Amazon but the ones I received do NOT do adaptive fast charging and weigh 3g (10%) less than genuine Samsung adaptive fast chargers. Requested replacement and the replacements are also bad. If you scan the QR code you get garbage like "aaaaaa aaaaaa" while real ones give you data like "GH44-02708A+R37G8F0PH01RT3". Pictured is one of the bad ones I received on the left, and a real one on the right (with the cable plugged in).
