this logitech mouse and keyboard combination is an extremely good buy. the wireless build in extremely reliable, i am typing with this keyboard right now. the batteries will last for a very long time, longer than expected. The keyboard will last for months, even on continuous usage. the mouse will not last as long, but at 4-6 weeks, the mouse will last for pretty long too. The wireless adapter is quite long, so you can put the wireless receiver pretty far away if needed and still have a usable keyboard and mouse. for gaming, the setup is very good. HOWEVER, there is a very very slight delay in the keyboard that make make a difference in twitch-based games. But if used for normal everyday typing, working, or photoshopping, the keyboard and mouse will be more than exceptional. If wired keyboard and mouse are bothering you, then this is the buy for you. the usual great logitech build quality is present in this product.
