I think this is the best tenkeyless keyboard out there. It strikes a perfect balance between the small form factor of a mini keyboard but without sacrificing the arrow keys and even includes a few extra functional keys like Delete, PgUp and PgDn. When I'm not at work I can live without a numpad, and the extra space that leaves for using a mouse is awesome when gaming - living without arrow keys would be, at least for me, a lot harder. The build quality on this keyboard is top notch - even if it is plastic, it feels solid and has a good weight that keeps it in place on your desk. The keys are also all replaceable should you choose to really customize it, and the keyboard comes with a few extra keys in a random colour along with a space bar featuring the Chinese zodiac for the year it was manufactured, giving this keyboard a really nice dose of personality out the box. The wide choice of Cherry MX switches to choose from also means you can get one that feels just the way you want it to - this particular one has extremely fast response time, I barely have to push a key to get it to register. Perhaps the biggest selling point for me was that this keyboard requires no additional software - the macros and lighting effects are all controlled by the keyboard itself. This means no dealing with proprietary programs from the manufacturer that, let's be honest, we all know are garbage - some brands in particular seem especially notorious for crashing or taking forever to load every time you boot. Not an issue here. The slight downside to that is first of all, you obviously lose any game specific lighting effects, if you're playing a game that would highlight particular keys for you automatically. Secondly, the built in method of assigning macros or switching light colours can be a bit daunting at first, involving lots of key combinations in exactly the right order. Keep that manual handy though and you'll figure it out - honestly I think it's a very small price to pay for not having to deal with unstable, bulky extra software.
