I don't usually buy Revain products when it comes to tech peripherals as there are so many well-known, well-known brands in this space, but I'm glad I I decided to. I needed a one day delivery but the product itself exceeded my expectations. That's significantly less than I expected. Of course, there are greater possibilities with additional adapters such as USB-A ports, additional USB-C ports, etc. But since my devices only lack an SD card reader, this is exactly what I need. It's made of plastic, so don't get your hopes up on the build. For plastic, it feels pretty strong and durable, and the cable is thick enough that I'm not worried about it bending and wearing out. I still keep it in a case just in case, but for the average user the build is more than enough. It's very easy to use, just plug and play (although for some reason the cards are inserted upside down, so don't try to insert them too far and wrong!). Speeds are on par or slightly slower than the legacy port built into my old device, so I'm perfectly happy with the performance for an external adapter. If you don't need extra ports besides SD, feel free to buy this one.
