New keyboard, replacement for about 7 years used Logitech G910 Orion Spark, which was excellent, but the switches on the Q and W keys were on their way out. The massive difference is mainly the size, the G910 was huge, this one is about 12cm narrower, so I'm getting used to having my hands closer together where I need the numeric part - e.g. piloting a helicopter in the GTA. Otherwise, I have no problem with the key layout compared to a full-sized keyboard, the keys themselves are normally large with normal stroke (I don't like low-stroke) and it's as comfortable to type on as any other keyboard, perhaps only with the DEL key do I occasionally fumble. I'm a regular user, so I don't notice any significant differences between the Snow switches and the older ones from Logotech, they both feel the same except for the slightly different sound, only Asus doesn't have the smaller "bag" to the sides that the G910 had, but it didn't bother me in real life. I've only been using it for about a week so far, I can't say much about battery life, brightness is 50% and falling asleep after 3 minutes, the battery still shows 91%, but it will be individual depending on how much you spend on it daily. For me, I'm looking at a little over a month and a half. As far as wireless is concerned, I see absolutely no difference from a wired keyboard in response or anything else, it just works exactly the same. I just have a lot more room on my desk than before, it's about 12cm narrower than the G910 was, and I don't have to have the cable stretched out: -) The armrest is better than the G910, soft, magnetic, more comfortable for me. The advantage with Logitech was that there were two sizes to choose from, but it was hard plastic. I rate the Asusáckou one better, the question is how long it will last before it gets squeezed or torn. Otherwise, the package includes two spare switches, a pair of pliers to pull out the keys and switches, a second space bar with the ROG logo, a plated soft cable and some stickers. None of that was the case with the G910. As far as waking up from sleep is concerned, it's just immediate. I don't get it, but no matter what I click, it just responds immediately. So there is no prolonged awakening. As for the quality of workmanship, I have no idea how to rate the materials, the keys are nice, nothing squeaks, the feet look solid, I haven't tried bending it or any other crap from the net. I'll come back to the backlight, it had a slightly better G910, where every key in the letter was beautifully lit. Here the light shines through between the keys, which slightly evokes cheaper models that only shine between, but that would be by design. On the G910, each key was recessed, here they're above the surface, which has an advantage for cleaning, knocking out crumbs, etc, but just makes the light shine through more. It took half a day to clean the G910. That's all I can think of: -)
