Bests & Worsts Reviews from Amazon

I received this in the mail and my first thought it was an empty box! It was that light. Cool, I like light! I'm a typer, not a gamer, and I thought I researched everything about mechanical vs membrane, lighted vs not, wired vs wireless, etc... little did I know about the minute differences between layouts, a CRITICAL ERROR on my part, so this review may help those like me understand the difference before purchase. Pros: 1) Feel of key press is very comfortable and very easy to type 2) Back lighting is cool, steady on, different colors across the keyboard... pleasing 3) Keys at a comfortable height, fairly low profile, not sitting way high like some other keyboards 4) Slightly smaller footprint which I really like Cons: 1) ISO keyboard layout, NOT ANSI! I had no idea the difference, I only see one little comment from a user about it being an ISO layout. I wish someone had written this review before. In the US, we typically use the ANSI layout. What's the difference? The ANSI layout has a one-line elongated "return" key. The "|" "\" key is directly above it. However, on an ISO (European) keyboard, the "return" key takes up two lines, thus the "|" "\" key has to move! Normally ISO moves it between the "z" and "shift" keys. But evidently KLIM and some others put it beside the "return" key. This means when I go to hit "return", I hit the "|" "\" key, and I mean EVERY TIME! Talk about frustrating! I still have ANSI keyboards I use daily so I can't simply "adjust". This simply will not do. This is a drastic difference to a typer! 2) ANSI keys are larger, physically 5/8"... this KLIM and other ISO keys are only 1/2"... (that's right, I measured!) To accommodate the different layout, ISO keys are smaller and it's noticeable to a fast typer! I often hit two keys at once, where I never do that on an ANSI keyboard. Another drastic difference to a typer. 3) How the light shines through the keys, some keys are bright, others not so much. From directly above it looks fine... but who types directly above the keyboard?! With the kickstands up in the back and at a natural angle, the symbols on the top row of numbers, for example, are very difficult to see. The larger single letters are easy to see. But it's difficult to see a lot of keys with symbols and smaller letters, like "insert", "delete", etc... 4) I thought I'd use the "on/off" switch on this keyboard to turn it off if needed, but really the light up feature needs to be on all the time even in the day. Without high contrast letters, it's difficult to see these during the day! But I realize this may be a necessary downside of any lighted keyboard. Turns out I don't mind the lights being on all the time, so I don't really use the "on/off" switch, something I thought I would! I gave a 4 star rating because I still like the look and feel of the keyboard, and I can see most of the keys in a dark room at night which is why I bought it. But it's not ideal to see all the keys clearly. And I take responsibility for not understanding the difference of ISO vs ANSI layout, I know now... but I wish it was more clearly described so I could have researched it before purchase. And as I type even now with it, every return I type is preceded by the slash key (oops!), then delete (crud!), then a deliberate reach (ugh!) for the "enter"... every. single. time. If you are a typer, look at the pictures of the keyboard you want to purchase... and look at the "enter" key as a first clue. But it's not only that, some are hybrids now, with a bigger "enter" key, but the extra key is NOT beside it, it's somewhere else, which may or may NOT be a problem. Just know what you are buying!
