I contacted customer service to obtain warranty service, they then offered me a replacement with a different model. I then asked why another model if I bought is still for sale on their Amazon page. No response, and their share and the next day I get an email from Amazon telling me a refund I never asked! Reimbursement is excluding shipping and the current price of the charger is double that I paid.
So I contacted the seller by 2 times for an explanation, cancel the refund and benefit from a standard replacement product which, I recall, was just 3 months of use. No response from them after 10 days, hence this negative comment.
I HIGHLY recommend the purchase of this product of poor quality and that you will be faced with an incompetent service. Avoid at all costs!
