I’ve had my keyboard for just over a year. After having recurrent tendonitis in my right arms for several years now, I am very particular about having the “right” setup for an ergonomic keyboard. I enjoy the Delux for the following reasons:- Chiclet keys are awesome for a fast typing experience. I love being able to fly all over the keyboard to type out everything easily. I don’t have to expend any extra time or energy to depress a key. Unlike other reviewers, I have not had a single key break off but maybe I got lucky.- Compatible with both my MacBook Pro and my office PC laptops. The Bluetooth connection and the firmware for this keyboard were a breeze to get setup for both of my laptops. There is only the slightest lag up startup of my computer or after the system was in sleep mode for a little bit. It even works well with my iPhone - which I am typing this review with the keyboard paired to my phone right now! The function keys have always worked really well for me - I just have to press the “Fn” key if I want to use the function for something (ex. Refreshing a webpage would be “Fn” + “F5” but adjusting the Brightness would be either “F1” or “F2” without having to use the “Fn” button).- A major criteria for me was to have a key with a light to indicate CAPS LOCK. In computer mode, it works really well but with an iPhone, the Caps lock key toggles back and forth between languages. The red light on the center of the keyboard indicates if it charging which is also a nice indicator. The number lock and cap locks features flash up on the screen when you press the key to let you know if you have toggled them on or off. The key to lock your work station is nice - I really missed this feature when I was playing around with another keyboard.- Media buttons are something that I never knew I wanted or needed. These are centrally located on the keyboard so I can quickly play/pause my music or video and the volume buttons are advantageous as well.- The rechargeable battery life is insane! I think I only charge this once a month and I only have my back light on about 15-20% of the time without it being charges. If you have a USB cord plugged into your docking station or laptop, you can simultaneously charge and type with your keyboard. Also, a keyboard with a rechargeable battery was another really important criteria because I think they last longer than the battery powered ones and (depending on who you ask) it is more “environmentally friendly” in the sense that you don’t so much disposable battery waste.- Backlight option for when I want to work in a more dimmer environment (I get migraines sometimes). Honestly, not a single keyboard showed up in my search when I first bought this keyboard with a backlight function. It’s true that you had to be careful to only purchase the black version of the Delux but now I believe the white/Mac version of this keyboard comes with a backlight feature too. I have not used that version.- The leather-like palm rest is so nice. It’s not cold to the touch and it doesn’t get your skin stuck to it either.- Adjustable legs are nice for me to change my wrist angle with my adjustable desk.- Size factor is also great because I get a less wide keyboard which allows me to set up my ergonomic mouse right next to it in my drop down. As an engineer, it was very important to have a deck after number pad. Also, if I ever have to transport my keyboard, it smoothly goes into just about any backpack - even the smaller 13” laptop sizes.Most of my cons below are related to material quality:- Keys get a high shine after a prolonged use. I did not expect my keys to become this shiny so quickly.- The palm rest pleather is peeling off. I don’t know how many more months/years the palm rest has ahead of it.- I wish the num lock key also had a light (like the Caps lock key).- Sometimes I miss having the dedicated Home/Scroll Lock/Insert/Print Screen/PgUp/PgDn/End key block. They are mostly still available in the number keypad. I also like the key that allows you to highlight the entire word that your cursor is on and then open up the menu that you usually have with a mouse’s right-click. This function really helps me format proposals while also proofreading them faster.- The dongle has too weak of a magnetic. I already lost mine somewhere during the course of my life… So until they change the design, make sure you tape down the dongle to the back of your keyboard if you don’t want to lose it!Overall, for the money that I paid for it when I purchased it, this keyboard was a bargain compared to the other keyboard at the time. Now the price has come up and I have tried shopping for other keyboard but nothing beats the typing experience I have with this keyboard.
