I bought this product with lots of skepticism but it has surprised me. I liked the pink strap color and placed an order. Received product in two days. The fitness band is very easy to charge as it requires no external chords. The in-built USB dongle makes it easy to just plug and charge from any USB port. Charges pretty fast in less than 2 hours.

Overall, I am very satisfied with the product and quality.
