Apparently people get more excited about keyboards than I previously realized, who knows maybe even some of you guys do. I figured since we have quite the collection of tech enthusiasts it might be worth writing this review up.
Since I value my typing (and gaming) experience to some extent, I spent a lot of time looking for the "perfect" keyboard and came to the conclusion every brand has quality control issues, either due to the apparent size of their market or the simple fact that they are quite poorly put together. A particular stand out for bad quality keyboards however is anything Logitech.
Logitech's Romer G switches have little holes their keycaps fit into, unfortunately this leads them to snap off. I counted about 5 different instances where this occurred in my G910. Granted, the board itself isn't the worst. I took it apart and examined the soldering, even soldered a bit onto it for fun. Seems like they do have pretty good soldering QA. However, their keycaps leave a lot to be desired. I'm not sure if that's planned obsolence or what, but I'd stay away from them. Another issue is that the Romer G switch means that the keycaps are proprietary to some extent and rarely ever will a custom built keycap set appear on the market.
So I started to look around for other options; I'd heard of the K70 and didn't like the look of the board aesthetically if I'm honest. However, I thought I'd give them a chance since they were on sale and I quite liked the volume roller.
Some brief observations; I hear a distinct "spring" sound when typing. Presumably this is from the spacebar, maybe the stabilizers within the keyboard. Overall however the keyboard feels quite nice, and reminds me of my Cherry MX Brown switch experience.
I don't really care about my keycaps and what type they are (I've had ABS, PBT, etc etc.) but the keycaps are pretty soft and feel easy to type on for extended periods of time so far. I don't really miss keystrokes and I'm pretty happy with the typing experience on these Cherry MX Red switches; they're pretty quiet and similar in volume level to the G910. I was concerned about volume level since mechanical keyboards, while pleasant to type on, can be bothersome to other people within the house or even yourself.
So if you're not familiar with the commonly mentioned brands, here's a few; Ducky, GMMK, and Durgod. I briefly considered a Ducky keyboard before seeing that it was out of stock, lacked a volume roller (I genuinely love my volume roller, and missing it would be like missing a key), only came in the TKL (tenkeyless i.e. no number pad on the right) variety, lacked media keys, no braided cable, had no LED's, not as much user software, entirely plastic construction aside from a steel backplate (anything metal is good), not certain about their keyboard drivers if they even exist.
The pros of Ducky are that it doesn't seem to have too many quality control issues, however apparently a tiny bit of water will fry the Ducky keyboard completely according to the current top amazon review. Generally these "bad" reviews on amazon do point out the real issues with keyboards, for example the G910 top bad review points out the issue that cropped up in my G910 keyboard; with the keycap stems breaking off into the Romer G switches, preventing any new keycap replacement from entering into the switch properly and requiring you to use a soldering iron to partially melt and pry or pull the plastic stem out.
GMMK, this brand had quite a few things going for it. For example, the fact that its switches were hot swappable (pretty cool), the questionable part came when reading their user reviews. It seemed like quality control issues cropped up quite a bit in their keyboards. Apparently they have issues with their cable, a common refrain in the bad reviews being that the slightest bump can disconnect their cables. This raises the question about faulty electronics and or wiring. Which really makes me hesitant to buy such an expensive keyboard with faults like that.
Durgod Taurus was the keyboard I ordered, unordered, ordered, unordered before finally settling on the K70. It's a very good keyboard, but again there are slight quality control issues with the added drawback of an unresponsive seller on amazon (where I would have ordered from). This made me a bit sketched out by the prospect of ordering it, and the return process. Plus it was a TKL keyboard, and I wasn't sure if I would like the spacing for my hand size and the fact that it had less features for the price.
My little venture into the world of mechanical keyboards resulted in two clear options; Corsair or Ducky. You'll notice that on certain sites there is a large following for either one of these keyboards; maybe its their marketing teams? I'm not really sure. Anyway, it's generally down to what you prefer and are looking for.
It doesn't really seem like you'll get an absolutely "perfect", "buy it for life" type of keyboard but you might come close with one of the two assuming you don't spill water on your Ducky keyboard. Hopefully this helps one of you.
