Adesso SlimTouch WKB-4000

The Adesso SlimTouch WKB-4000 series has two members, the traditional 2.4 GHz RF WKB-4000UB version and the Bluetooth WKB-4000BB version. Other than the communication mechanism, both devices share the same external hardware design. These 87-key wireless keyboard / touchpad combos use 2x AAA batteries and offer up to 30 ft. range.

The keyboard layout is the same as that of the SIIG JK-WR0312-S1, except for the proper positioning of the Ctrl and Fn keys. The numeric keypad is also multiplexed with the traditional keys, activated by a combination of the Num Lock and Fn keys. Similar to the WKB-3000, there is a LED indicator (at the top right corner instead of the top center) to indicate whether the Num Lock key is active or not. Therefore, the ease of use factor is much improved over the SIIG version.

The attractive feature set of explicit power switches, auto-sleep after an inactivity period, secure receptacle for stowing the USB key and a Connect button to alter the communication channel is also available in the WKB-4000 series. For the Bluetooth version, a Bluetooth receiver is supplied, but I also tested it out successfully on various PCs and tablets / smartphones with in-built Bluetooth capability. The only requirement was that the initial pairing had to be done with some other input interface being active (particularly for the PCs which didn't have touchscreens). Otherwise, the keyboard even worked at boot time on those PCs without the Bluetooth receiver plugged in.

The scissor-switch keys of the WKB-3000 are retained in the two keyboards. Subjectively speaking, I enjoyed typing on these keys more than the WKB-4400's membrane keys. The 3" x 1.75" touchpad in the WKB-4000 units is also bigger than the WKB-4400's 2.25" x 1.5" version. Hassle-free one-handed operation is also possible. The touchpads could do with some gesture support, but that is not much of a deal breaker. All the keys are proportionally sized and present no learning curve to traditional keyboard users. All in all, the two keyboard / trackpad combo units could become ideal HTPC interaction options if they did away with the multiplexed numeric keypads.

The Bluetooth version is available for $70 on Amazon, while the vanilla RF version is retailing for $60 on Newegg currently.

    Very interesting product category I haven't looked into before.
    Found a typo in page 2:
    "Adesso's advantage that the kit can operate in one of 8 different frequencies in the 2.4 GHz band"
    Should have been "Adesso's advantage that the kit can operate in one of 8 different bands in the 2.4 GHz frequency"

    The built in balls of the wireless keyboards are tiny, resulting in more thumb action, despite adjustments in acceleration, which can throw off "zeroing" in on your intended click space.

    That and one cannot game in such a manner, which is a double bonus of an HTPC (but people are thinking HTPCs should only be for media and music).

    actually no, it should be in one of 8 different channels in the 2.4 GHz band"
  • omgyeti - Thursday, October 23, 2014 - link

    Those channels are bandwidths centered around 8 different carrier frequencies. So "8 different frequencies in the 2.4GHz band," as it appears in the article is perfectly acceptable.

    Specifically, the Logitech M570 as a more better means of HTPC control? Coupled with a inexpensive (preferably Logitech with Unifying receiver compatibility) one can have a full keyboard, unhindered in typing with a cursor drag device that is unhindered by any couch or any necessity of using a coffee table,

    And it is worlds better than a finite trackpad versus a drag space of a sphere.

    Did you even read the review? Adesso SlimTouch WKB-3000 features a trackball. The M570 is awesome (we have two of them), but ultimately it's clunky to have two wireless peripherals unless you really need them.

    We've been using Logitech K400 keyboards (3x) for a couple years now and they have performed flawlessly. They're perfect for navigating the web or XBMC, even some light gaming, but anything involving more than four keypresses gives it trouble. We've only replaced the batteries in one of them in almost three years. $25 is hard to beat. All our HTPC hardware is hidden away behind walls/closets and the keyboards have no problems operating, even with all three going in the house.

    I only break out the M570 if I want to play an RTS on the big screen, but it's so rare as to almost never happen. Otherwise, I just play on my gaming rig in the office with a real mouse/KB combo.

    The trackball in the built in keyboard is smaller, thus more thumb action and need more target "zeroing" if one were to adjust the speed and acceleration to move a great distance to compensate.

    Bulky? Being separate, one can solely navigate the HTPC for media sans keyboard. The only time I ever use a keyboard for media, is to type in searches. Otherwise, it really is not much used in an HTPC setup.

    And gaming, batteries still going strong in the trackball I used. Plus, the built in trackball, leaves your hands in a very uncomfortable playing position. And I also mentioned the built in trackball in a reply of another comment, I meant to be a part of this one since there is no edit feature.
  • nathanddrews - Wednesday, October 22, 2014 - link

    I said clumsy, not bulky. Needing to use two separate devices is often enough to dissuade people from using media PCs or HTPCs.

    We clearly have different expectations from our media/HTPCs and our peripherals. Have you considered duct taping your M570 to a keyboard? :P
  • Imaginer - Wednesday, October 22, 2014 - link

    No because that is UNCOMFORTABLE.

    My M570 rests to my side, arm relaxed to the side. This is coming from a person that also detests controllers because of the hunched convergence.
  • SirGCal - Wednesday, October 22, 2014 - link

    I have two M570's also, but NOT on my HTPCs (of which I have 3). As they mentioned, we would prefer one-hand operation. I DO have a solution but it's also the best of the bad options. It does work though. What I have is similar to this (but it is different, this might be better/newer):

    The HTPC is supposed to be short-access, not accurate (gaming) necessary. And a device like this is super-easy to click on a single file or program to execute and do so with one hand. I have to move my thumb just as much with that device as I do with my Logitech track ball. But in the end it is vastly better either way to have just one device for the HTPC and if you truly feel different, great for you but that's vastly in the minority.
