Cougar Deathfire EX Keyboard and Mouse Combo Review

Rating: 8.0.

Getting a set of quality peripherals can often set you back a fair chunk of cash – and that's on top of the cost of your PC. Cougar realise this and hope their Deathfire EX keyboard/mouse combo can provide a good alternative to buying the latest peripherals separately. Priced at £49.99, the Deathfire EX combo features a ‘memchanical' keyboard and a lightweight gaming mouse – but are they any good?

It is true the latest-and-greatest peripherals can cost a lot – just look at the ASUS ROG Claymore (review HERE) which is priced at a whopping £199.99!

While the Cougar Deathfire EX keyboard/mouse combo won't be able to offer the same feature set or build quality, it is much cheaper – coming in at £49.99. For this price we would still expect solid performance, though, so let's dive right into the review and see just how good this keyboard/mouse combo really is.
