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.

    How does this compare to the CM MasterKeys Lite L Combo? Both are rated pretty close(7.5 for the CM).

    I actually really like the look of that and for £50 quid I’d probably pick one up for my wife’s PC, She’d probably find one DPI setting for Star Dew Valley and never change it again and the cat would be hypnotised by the lights.
    However….MEMCHANICAL is not a word……I hate marketing bullcrap. It’s a membrane keyboard, nothing wrong with that, membrane keyboards can be really good especially when another person in the room is trying to chill out and read a book. What Memchanical says is I wanted to be mechanical but I failed to even meet the minimum standard. I’d have called it the Super Ultra Mega Master Invincible Elite Membrane Keyboard, all legitimate words straight out of the dictionary.
