Brilliant keyboard, tactile keys make typing pleasurable and easy on my fingers, plus the trackball instead of mouse has reduced the strain on my wrist. Not having a wireless connection is also a bonus, there's no "black spot" on my desk for this and, in the long run, not having to replace or recharge batteries is good for the environment. It's well made and feels robust, so I'm looking forward to many years with it.Delivery time was quick, packaging was robust, it arrived with zero damage and early. Can't ask for more.

La tastiera soddisfa egregiamente il suo compito. La pressione dei singoli tasti è davvero soft e reattiva ed il trackball è comodo da utilizzare e sensibile sin dai minimi spostamenti (i tasti destro e sinistro sono perfettamente posizionati sotto la sfera e la rotella di scroll è tarata con il giusto scatto di scorrimento)Il prezzo però mi sembra un po' altino

Cumple las expectativas, aunque el tacto de las teclas no es agradable, eso sería una mejora significativa.

The lighted version has full individual key RGB lighting! It has 6 different lighting modes including a very catchy raindrop mode where each key lights in a random colour then slowly fades (about 1/2 the keys lit with different colours at any time). It also has solid light modes of different colours you can choose, and a breathing mode where a wave of colour moves across the keyboard. Finally, it has a mode where random colours emanate from each key you press and flow throughout the rest of the keyboard! Very fun to watch.The keys are true mechanical keys, smooth (no click as you press them), but of course noisy as you type and each key hits the bottom of its travel. Very comfortable though. And enjoyable to press, you feel like you're pressing something of value and luxury with every keystroke. (This is my first true mechanical keyboard.) The trackball is amazing, full size trackball, what more can you say? Beautiful red colour, smooth texture, and smooth feel to rotate. Two DPI settings (Fn+F9), modern normal fast and very fast. The wheel is notched and tilts, and the mouse buttons have a good click to them.The layout of the Ins/Del/Home/PgUp/PgDn/End is quite logical I think. You use Fn+ Ins/Del/Home/PgUp/PgDn/End to change the light modes, although this is not labeled on the keys unfortunately. Fn+F12 for colour selection, and Fn+F11 for brightness (4 steps). Max brightness is sufficient for a reasonably lit bedroom, but it's not super bright. Fn+Arrow Keys adjusts the direction of the breathing pattern too.The keyboard is a little thicker than usual probably to make space for the thickness of the trackball, but it's nothing major. There is one little quirk with the trackball, though, and it's that it seems to have a sleep mode. If you don't touch it for a minute, it takes about a third of a second to wake up when you touch it next time so the first bit of movement is lost. Seems completely unnecessary for a wired product.The overall feel and weight of the product is very good. The lights turn off when the computer sleeps, and when it wakes up the previous lighting mode continues. However, when you switch lighting modes on the keyboard (eg. away from solid colour to another mode, and then back to solid colour), the solid colour you had chosen is not remembered. (It defaults back to red.)Wish list for me would include duplicate mouse buttons on the left side/edge of the keyboard, so that I can click with my left fingers while my right hand is on the trackball, without having to lift/move my fingers off of it to click the buttons below. Back and forward buttons on the left and right side of the trackball respectively. And maybe even duplicate mouse left and right buttons above the trackball, for maximum flexibility of which fingers to click with (you pretty much always have to use your thumb to click the buttons below it I find). Having duplicate mouse buttons 1 & 2 (left and right) on the left side/edge of the keyboard would also help in being able to make precise, extended movements of the ball while holding and releasing the buttons at the precise moment, eg. when photo editing or selecting files.The trackball is amazing. Why not have a whole trackball in the same space as an standard keyboard? Great for using the keyboard on your lap and having everything in one place and in one unit.

I WAS A LITTLE WORRIED ABOUT THE PACKAGINGBUT THE PRODUCT WAS IMMACULATEI ACTUALLY THINK IT MAKES MY TRACKBALL WORK SMOOTHERVERY GOOD QUALITY, HIGH POLISHYOU NEED ONE, GET THIS ONE
