I bought an Apple 20w charger which was cheaper than found elsewhere...for a reason. I received it but found it to be fake. It produced an inconsistent power output which causes damage to the phone overtime. I complained and was immediately refunded. The seller said 'Hi my apologies I have sent a full refund.' I have reported this to OnBuy using the form (because they must have so many counterfeit products they need a dedicated process for them). They haven’t replied and the product is still being sold MONTHS after i have flagged it. I have filed another form today. Do not use this company. They know their sellers use fake products and don't want to act on it. STAY AWAY
