I will split this review between the mouse and keyboard.
The keyboard is very much what you would expect for this price, it feels cheap and the plastic is really thin, however it works perfectly fine. Im pretty satisfied with the keyboard.. even though it feels and looks a little bit cheap its light weight and generally quite comfortable to type with. 2/5 for the keyboard.
Im a lot happier with the mouse than what i am with the keyboard. The mouse feels a lot sturdier and generally better made. It fits nice in your hand it and runs smoothly.
3.5/5 for the mouse.
Overall i would say, if you are looking for a cheap keyboard and mouse with no fancy gimicks ect then this is perfect. If you tend to use the keyboard and mouse extensivly i would maybe consider looking else where as i doubt these have a lot of durability. I would not recommend these for gaming either.
All in all, pretty decent for the price but if you have a bit more to spend then i suggest you look at other products.
