The SteelSeries Rival 3 is the best budget gaming mouse in my eyes - and I've even written articles to that effect - so imagine my surprise and delight when I spotted the even better wireless model is down to £25 at Amazon UK. That's £30 below its UK RRP and a fantastic deal for a mouse that offers both 2.4GHz wireless and Bluetooth connectivity plus an 18K optical sensor and a comfortable symmetric shape.
