Not only 5 stars for the product, but 5 stars for the company. I had previously purchased an anker car charger that stopped working within the first year of having it. I was disappointed but it is what it is. Left an honest review on the old product but I still believed Anker to be a quality company so I purchased this charger. It works perfectly, fast charges my galaxy s8. The company noticed my review and contacted me to replace the original charger. I thanked them but said I had bought a new one already. So they went above and beyond to refund me the price of the new charger! Again, 5 stars for the product and 10 stars for the company and customer service. Anker customer for life!
