Whilst the idea behind this product is great, the execution of that idea is flawed in so many ways.
The key layout whilst logical, is very widely spaced, and I have quite large hands yet I found it a struggle. Basically the numeric 1- 3 keys (usually the most important in fps) are virtually impossible to hit whilst using the direction keys owing to the reach. To compound this error, the numeric keys are little oblong strips, not easy to press round buttons.
Then we have the keys themselves. Not only do they suffer a long travel to depress them, but they have a horrible on off action, making soft precise control impossible.
I ended up giving mine away to a friend after buying the far superior Zboard merc gaming keyboard. A few months later I asked him how he was getting on with it, he told me he had gone back to using a regular keyboard as it was better for gaming.
A great shame because cyber snipa's gaming mice are fantastic, but this product is sadly a bit of a duffer, and in need of a major reworking to live up to its promise.
