[EX Q]: Asked for IPhone 6s Plus and was sent IPhone 6 Plus. Have replaced manny in the past but never from this saller and won't anymore from this saller.
[EX A]: This seller just gives u what they have in stock even if it's thee wrong pruduct

[EX Q]: This product worked great for about 6 months. After that, it stopped working. I contacted the manufacturer for warranty and received no response. They claim a 12 month "worry free" warranty. Unfortunately, I learned the hard way. Pay a little more for a better product.
[EX A]: Utter garbage. Save yourself some money and buy something else. Customer service is a joke

[EX Q]: I would give this light 5 stars for the price except it arrived with a 4.2 Volt Battery pack and an 8.4 V charger?? The charger does not shut off since it never achieves the 8.4 V charge state. I am also concerned about the battery going thermal runaway? I have not noticed it getting too warm but not happy with the mismatch.
