Perixx PERIBOARD-335RD Wired Ergonomic Mechanical Compact Keyboard - Low-Profile Red Linear Switches - Programmable Feature with Macro Keys - Compatible with Windows and Mac OS X - US English

EDIT: The left side of the keyboard didn't actually fail. Rather there was some odd interaction between the keyboard and the software the encrypts my hard drive sprang up out of nowhere. When starting my computer after it has been shut down and before the operating system even starts to load I have to enter a pin number that along with the chip in my badge will unlock the hard drive. For reasons I don't understand this particular software and this keyboard after about a week of working together fine, just decided to not play nice with each other. As a result I had to use the laptop's own keyboard to enter the pin. However, once unlocked and the computer fully booted up this keyboard worked just fine, including typing in exactly the same pin number to log into my account. Still it was a hassle to open the lid of my laptop every time I needed to unlock my computer, so I did return it. However, this is entirely this keyboards fault and because other than one weird thing the keyboard worked great I am increasing my rating from 3 to 5 stars.ORIGINAL: I bought this to replace the latest of several Microsoft Sculpt ergonomic keyboards that I have owned. I love the ergonomics of the MS Sculpt, but the membrane keys just aren't very durable, so a Sculpt only last me a couple of years before keys start fail. Also the membrane keys lacked the nice travel and feedback of a mechanical keys. This keyboard seemed like an ideal replacement, even though I don't like wired keyboards. And it lived up to my hopes for it, at least while it still worked.The feedback of the mechanical keys are great and they take me back to the original Microsoft Natural keyboard that was my first ergonomic keyboard way back in 1995. I also really like that it comes in 60% tenkeyless layout like the Sculpt but with a better navigation section. I can't use full sized keyboards with a ten key section (even though having a ten key really helps my efficiency when entering a lot of numbers) because the additional width pushes my mouse too far to the right resulting in a very un-ergonomic position of my shoulder which causes impingement of the tendons in my shoulder. This results in my shoulder being quite painful by the late afternoon. Eventually constant irritation caused me to develop tendinitis.So everything was going great until after just a week the left hand portion of the keyboard simply stopped working. So I am having to send it back. It is only for this unreliability that am I giving this keyboard 3 stars. There being nothing wrong with ergonomics, value for the money or comfort, I am still giving it 5 stars in each of those categories. No manufacturing process is perfect and it could be that I just got unlucky to get one of the very few that failed early. So with all of the good features and Amazons easy return policy it probably is still worth giving this keyboard a try.

十字キーと、そのうえの6つのボタンendとかhomeとかが、一週間くらい経ったある日、突然反応しなくなってしまいました。他のパソコンでも同じだったので、設定とかではなく、本当に壊れてしまったんだと思います。それ以外のキーは使えます。一体何故こうなってしまったんだろう。気に入って使ってたので、とても悲しいです。追記。usb切替器を使っていたので、本体に直接差したら直りました。切替器が窓際にあり、その日の外気温が氷点下10℃くらいだったので、接続に変な影響が出たのかもしれません。

Possibly the best keyboard I have owned. Previous boards incl. Microsoft, Dell and Logitech. I mean, all budget tech gear is a compromise to cater for as many users as possible. Some just do it a bit better, or the compromise just happens to suit oneself better than it would others. This is particularly so when it comes to ergonomics. I live in the humid subtropics, so the wrist rest on this is good. It hasn't deteriorated in what, three years. All the keys still click like new. I think this keyboard, and possibly all Perixx boards, are made with better quality than others that are similar.I sometimes wish I had waited for the backlit model. It would have proved useful as at night I only have the screen to illuminate the keys used less often.

This is the best and the worst keyboard at the same time.The red switches are amazing, super light, no-strain, easy typing, just wow. Build quality- solid, very good bent shape both horizontally and vertically, high quality materials.But the wrist rest is horrible and even painful - if you place your hands on the keyboard in an ergonomoc, wrist-straight position, the palm of your left hand stands exactly on the sharp edge of the plastic. If you want both of your palms to rest on the wrist rest, you must bend your wrists inwards as you would on a regular keyboard, which defeats the purpose.The only sustainable way to use this keyboard is to find a very thin and flexible keyboard wrist rest and lay it over the edge of the keyboard’s own plastic wrist rest.If they improve the wrist rest, this would be the perfect keyboard for a variety of activities ranging from gaming to office work to coding

Will never use a normal keyboard again. So much more comfortable to type with.
