Pros: Absolutely amazing product. The front end is easy to use and has many configurable options. All the games look insanely good via HDMI. Firmware updates are constantly flowing in and easy to apply via SD card. You insert the SD card into the Retron 5 and get a key file which you upload to their site when retrieving the latest firmware. Once downloaded you just stick in the SD card slot in and it asks to start updating. I mainly use the Retron 5 for Sega Genesis games, but also have been playing Gameboy Advance carts.

Cons: The controller that comes with it is a bit sensitive and cheap feeling, but it works good enough. I mostly use the original Sega Genesis controllers.

Overall Review: Hyperkin is continuously updating this product with firmware updates. Nice!

Pros: Absolutely the best mouse I have ever owned. The customizable weights are a fantastic touch. The hardware controlled tracking speed is awesome and the scroll wheel is the smoothest action I have ever come across in a mouse.

Cons: The hardware controlled tracking speed buttons are right where I usually click the left mouse button so it takes some getting used to moving your finger a little to the right to click on the left mouse button.

Overall Review: So worth the price.
