Illumination being popular SteelSeries have not left anything out, different lighting effects including waves, steady colours, reactive (which fades from one colour to another) and colour shifting. Variations and possibilities are not limited with the colours and the design, a gamer who wants to match any colour or set up specific visual for games and macros will have great use with the SteelSeries Engine.
With macro recording it is fairly simple, you click the key you want and record the presses you want and its set. If you want to use standard keys you can select them from groups or if you like you can disable a key entirely.
Testing out the keyboard with Battlefield 4 brought out how smooth the keyboard is, without any click or noise, it felt completely different than other mechanical keyboards and does stand up to its name of being reactive. There was never a point where there was an delay or lag and movement in game I was always in control. Keys did in the heat of the action feel too close together which from time made me feel unsure of key presses. The W key does have bumps to help distinguish the key location but not some that is every noticeable.
Overall the SteelSeries Apex M800 is a nice keyboard. The price point at £160 might be a turn off for a lot of gamers which aren’t willing to pay for the higher end keyboard but the dedicated few will see the benefits of this keyboard. The low profile design and QS1 switches make it really nice to type on and use in game and the SteelSeries Engine has just the right amount of customisation to do exactly what you need from the keyboard with no extra frills. The lack of wrist support is something that it noticeable over long periods of time but if you have a spare support and can afford the price it is a keyboard that stands out in the market of mechanical hardware.
