I love Anker products because they are durable and very easy to use. Anker's Customer Service Team is the best. I have purchased several products from them. Portable chargers, headphones, Bluetooth ear buds and the sound is amazing. In fact I'm waiting on the delivery of the new slim sports buds as I type this message. Their delivery speed is the best. I won a mini core charger from them this last Christmas and it got lost in transit to me. I reached out to the support team and within days of receiving my email they sent me a replacement gift. I can't say enough good things about their products.
