Using this product since a year now. I must say it has one of the best camera quality in bright light. Htc sense feature is amazing. And also like the custom theme changing option. Surround sound quality is great and also can be more better. In phone storage of 16GB is sufficient for a normal usage and can also be increased with a memory card. Front camera is also good. Buttons at the side are reachable. It does not support OTG. Battery backup on a single charge for me is 12hours with all day on WiFi and some gaming with continous use of Youtube, Instagram, Whatsapp and Snapchat.
