Before I updated the firmware, it was doing some weird things.It would select a bunch of text and then another key press later, poof, gone. Plus, the question mark would work, but not the slash. Both are on the same key.Use the firmware on the left from the photograph.It was easy. Just download, and double-click the file for the update. Five seconds later it is done.I updated the firmware and everything was corrected. But, the fix did not last. It was only was fixed for a few hours. Maybe, because it has three different connection modes? I ran the firmware update file a second time, and it has now been almost a week with no problems.I was ready, with hundreds of dollars worth of keycaps, parts, and switches to upgrade this keyboard when it arrived.But, it is awesome. I am not changing anything.The keycaps don't cause my fingers to feel like chemicals are being leeched into them.All the keys are perfectly aligned. It sounds great. It was like $50.I am thrilled and want to try all of the versions of this Plus model. But, I'm not doing that unless they send them to me. I will buy them eventually if I "need" some more keyboards.Even, the space bar is fine.I'm not changing anything on this keyboard. No lube, no $200 keycaps, no expensive lubed switches, or greased stabilizer bars. I am not even switching out the stabilizer bars for upgraded ones.I may do a little "something" to the space bar.It's fine now, and doesn't need any changes.It's genuinely a great keyboard.The cable connection works, the dongle works, and most importantly when in wireless or Bluetooth mode, the keyboard does not "time-out", or "go to sleep".If I press a button on the keyboard, after not using the computer or keyboard for a long time, it immediately works, and the computer responds.I had an Epomaker TH80, and the Bluetooth would go into a "slumber" if nothing was typed for a few minutes or hours. So, I would start typing, and twenty seconds later words would show up as it, came out of hibernation.I don't need that, at all.This one is normal and stays connected.I don't know if it has any specific software to program it, exactly how you like. Or, if it works with existing keyboard programing software.At first, I thought it was too good to be true. Because it was doing weird things. Like, after pressing a bunch of buttons my screens rotated sideways, and I still don't know how to fix it.The keyboard is already programmed well. There are tiny pictures on a lot of the keys to represent what different "hot-key" actions do. They are enacted by the function key, and then that key or the windows key and then the key. Maybe, there are other combinations too? I haven't searched for a complete guide, yet.Great keyboard.I like the layout of the keyboard.The up, down, left, right arrow with the function key works well. The keys are the correct size, and it is easy to use. Just a right pinkie finger for the function key in the bottom right corner and then easy presses for the arrow keys.I bought the one that has Plus in the name.This keyboard is great, and I am very happy with it.I will leave this one as is. But, I have a lot of switches and keycaps that I need to put on good keyboards.I might buy another, to upgrade.This one is a perfect gift for someone looking to get into mechanical keyboards.It can be upgraded with different parts, easily, as this is a hot-swappable key-switch keyboard. The base structure is fine, and even without "expensive" upgrades, it could still be upgraded, cheaply. For, example sound. For, me this keyboard is very nice, and I am extremely happy with it. Keyboards go into the thousands of dollars, and this keyboard is not a compromise to me.I wasn't excited that the upgrade firmware was an executable file, and not a program with keyboard mapping software, and keyboard firmware capabilities.But, it was the easiest firmware upgrade I have ever done for a keyboard.I had to search on a couple of different websites, because this Plus model was not listed on one of the websites.This company didn't pay me, and no one asked me to write this review.I just know how expensive keyboards can be, and how much overpriced stuff there is.Like, with a lot of companies, this product could be great today, but later manufactured to "save costs". However, the one I got is nice.I almost bought a different keyboard, and then just before purchase, noticed the right shift key was tiny. Nobody, wants that.I wrote this long review, because I have spent a lot of money on keyboards, and I like this one, a lot. Especially, for $50.The plastic case does not bother me. Because, the keyboard is made well.This keyboard is heavier than the HHKB must have keyboard. But, that one it can get expensive quick. Because, you don't want their Bluetooth model, or their lubed "silent" version. Just the base model and do everything yourself. The Bluetooth Hasu controller is the most important upgrade, and is about $75.This keyboard is the "mechanical switch" version of the "dome switch" HHKB keyboard.Also, upgrade "dome switches" with different tensions are now sold. So, that keyboard can go past $600, easily, and that's if you only use the original case. But, if you get an upgraded custom case the cost just keeps going up.This keyboard has a nice weight to it.The HHKB can be almost too light, stock.It saddens me a little, when I see and listen to the review videos of keyboards in this price range.Some people can't afford, more, and just about anything is good enough. But, this keyboard, or at least the one I got is awesome. It "made" me happy, and I'm sure anyone who got it as a gift would be happy as well.

【打鍵音について】オフィスで利用を目的に購入、YouTubeのレビューで打鍵音が心配だったか、オフィスで利用するのに問題ない程度で、比較的静かです。若干のクリック音がしますが許容範囲です。併用しているKeyChron K2 V2茶軸より静かです。（あくまで個人の感想ですが）【Macとの相性】デフォルトはWindows用にキーが設定されていますが、Fn+Sを押すとMac仕様に変更できるので、Win→Option、Alt→Commandで利用できます。

Al principio todo bien, el teclado es muy bonito y muy cómodo, lo use como por 3 meses hasta que empezó a fallar inalámbricamente, no me duro nada y eso que solo lo usaba fines de semana ya que trabajo fuera de mi hogar y solo llegaba entre ratos los fines de semana. En fin, no lo compren, no dura nada. Al menos fue bonito y cómodo mientras duró

My only dislike is the lack of feet for height adjustment. It's a good height out of the box but the ability to further adjust would've been nice. The keyboard is extremely good. Feels super high quality, the switches feel top notch and the clicks are pretty quiet. RGB is solid, love the USB and type c ports on the back. Nothing to complain about besides the lack of adjustable feet. No double pressing issue with the keys either. Would absolutely recommend

excelente producto
