Software

Tesoro usually creates graphically fancy software packages, even if the user interface is simple and the options limited. This time Tesoro decided to go with a clean, simplistic design, but the software remains relatively unsophisticated for a keyboard of this class. It is however very easy to learn and use, with every option and setting cleanly arranged on a single screen.

At the top right side of the UI, the user can select between the “PC Mode” and any of the five programmable profiles. The PC Mode is the basic keyboard mode that disables all advanced functions and has the Gram Spectrum behaving like any ordinary keyboard. Each of the five profiles can be “Synced”, that is linked to a specific application, automatically engaging when the application starts.

 

The Tesoro Gram Spectrum is a fully programmable keyboard, allowing the user to freely disable or reprogram any of its keys. It is possible to either re-map a key, to launch applications with it or to perform a macro that has been programmed using the software. The macro recorder however is rather basic. Macro recording is initiated by clicking the "Start Record" button, all key presses with their time delays will be recorded, and then it will stop once the "Stop Record" button is clicked. The time delays and the sequence can be edited, as well as new key presses can be inserted into an existing macro. It is also possible to set the macro to repeat a finite number of times, as long as the key is being held pressed or until it is pressed again. However, the recorder is unable to record anything beyond keyboard keystrokes, such as mouse movements and clicks.

The illumination button brings out a menu of nine basic colors, plus a palette with any possible RGB color. The palette is very small and seems difficult to select an exact color, but the software also allows manual input of the RGB code of the color, allowing for precise fine tuning. Special effects can also be selected for the entire keyboard, such as a rainbow wave and “breathing” brightness effects.

 

Per-Key Quality Testing

In order to test the quality and consistency of a keyboard, we are using a texture analyser that is programmed to measure and display the actuation force of the standard keyboard keys. By measuring the actuation force of every key, the quality and consistency of the keyboard can be quantified. It can also reveal design issues, such as the larger keys being far softer to press than the main keys of the keyboard. The actuation force is measured in Centinewton (cN). Some companies use another figure, gram-force (gf). The conversion formula is 1 cN = 1.02 gf (i.e. they are about the same). A high quality keyboard should be as consistent as possible, with an average actuation force as near to the manufacturer's specs as possible and a disparity of less than ±10%. Greater differences are likely to be perceptible by users. It is worth noting that there is typically variance among keyboards, although most keyboard companies will try and maintain consistency - as with other reviews, we're testing our sample only.

The machine we use for our testing is accurate enough to provide readings with a resolution of 0.1 cN. For wider keys (e.g. Enter, Space Bar, etc.), the measurement is taking place at the center of the key, right above the switch. Note that large keys generally have a lower actuation force even if the actuation point is at the dead center of the key. This is natural, as the size and weight of the keycap reduces the required actuation force. For this reason, we do display the force required to actuate every key but we only use the results of the typical sized keys for our consistency calculations. Still, very low figures on medium sized keys, such as the Shift and Enter keys reveal design issues and can easily be perceptible by the user.

We were curious to see how the new, shortened “Agile” switches would perform and their quality proved to be satisfactory. The switches are significantly heavier than their normal Blue counterparts, though we should note that Tesoro does not claim that these switches should share the performance of the typical Blue switch. As the spring of the switches appears to be of the same size and type as that we found in Blue switches, the shortened stem probably “pre-loads” the spring, stiffening the remainder of its travel. We measured an average actuation force of 52.3 cN with a disparity of ±8.54% across the main keys, a relatively high but reasonable figure.

    Specifically with Red switches.

    If you have a microcenter near you, they have most mechanical keyboards in most switch configurations on demo! It's really a buy based on comfort decision. A cheap mechanical keyboard just isn't worth it after you consider you will have this keyboard for probably 10 years. I've had my das keyboard for 7 and all I've ever done is clean it by removing all the caps with a key puller and soaking them in soap overnight. I added red orings to further quiet down the brown switches from bottoming out "clank" so my partner isn't woken up late at night by the hammer.

    As far as the best mechanical keyboard under $100? Well, corsair, cooler master and many others have them in the $60 range with cherry switches. It's a gamble to go lower because you won't get genuine switches, which in all reality might be adequate, but again, why take the risk? Remember, you will have this thing for s decade just make sure you get genuine switches and a decently weighted keyboard.

    I have the Cooler Master Storm Rapid for lan party's, also with brown switches. It was $60. But it's a compact without a number pad, which honestly sucks for general use. For a LAN party it's fine, but even simple things like entering a login pin are undesirable without a numeric pad.

    So basically spend the extra $10 and get the full 104 keys. Maybe even spend another $10 for the TK model with backlit keys. Your still under $100.

    Do you plan to use anything but Windows? Because if you ever venture over into Linux, you lose major functionality on most keyboards. They are dependent on a Windows-specific utility for settings and optimization. Exceptions are the CODE keyboard and anything from Ducky.

    Cooler Master QuickFire is what I'd recommend. Not so much bling, just the essentials.
    They come in three size variations, I think. Full size, ten key-less and ten key (where the arrow key section is removed/integrated into the ten key section).
    The backlight LED's doesn't do many fancy things except for bringing light. And they're the colour of the Cherry MX type in the keyboard, though the ones with brown switches had white LED's.
    The build quality is pretty flawless, I think. A thick metal plate inside makes the keyboard sturdy as a rock and gives you a distinct feedback on key presses.

    RGB...Rainbow Dash fans everywhere are probably getting excited to see another keyboard that can make playing computer games in dark, lonely apartment living rooms more comforting.

    If the keyboard doesn't have a wrist-rest, I automatically have zero interest.
  • Samus - Monday, August 22, 2016 - link

    That's ridiculous. You can add a custom wrist pad to any keyboard, even mechanical ones (which require a thicker pad because of their additional height. Graffiti makes some really nice ones in different materials and surfaces, and you can even buy wood wrist rests made in Japan.

    Hi Fylladitakis, Can you suggest a Ten key less (87) Wireless Keyboard (Ideally Mechanical). I tried searching but couldn't find any. There are full keyboards available but not TKL. I found few which say TKL wireless but they are basically HTPC keyboards (without independent Home/End/PgUp/PgDn keys). Thanks...

    Varmillo VB87M ?

    I dont have first hand experience, but it seems decent.

    https://mechanicalkeyboards.com/shop/index.php?l=p...
    (available in other switch types)

    It's often on massdrop (drop active for 8 more days)

    Awesome, Thanks a lot, this is exactly what I am looking for. One more question, I don't play games and primarily looking for Development work (and ideally should be silent so not to disturb others). So, Cherry Mx Brown would be ideal right or do you think other switches serve me better?
