I never liked the messy OTG cables in between my phone and pendrives, so it's perfect for me :P I've been using it since a month and it's working quite smoothly. Read/Write Speed is around 50-60 Mbps. Pretty good. Design is okay... small, easy to carry but it can be improved. It takes a little practice to smoothly switch between the two connectors. Considering its price and what it offers it can be considered a value for money but it could have been better if it had a cap to protect the connector from oxidation and dirt.
