    nice stand, quick easy setup
    Size: Quad, Style: Glass Free Stand
    nice stand, easy setup, I like that you mount the bracket to the monitor first and then hook it onto the stand. This makes for a quick and easy setup. You do have to wrench down on the screws to keep the monitors from moving. Also you may want to have 4 of the exact same monitors so they all are at same height. I have two that are the same and two others that are different so they dont all mount at same level. I plan on ordering monitors to match.

    Fantastic upgrade from my original stand. Base is a little bulky, but stand is versatile and sturdy.
    Size: Single, Style: Free-Standing, Size: Single, Style: Free-Standing
    Amazing value for this stand. I needed a stand with more degrees of freedom than the original one that came with my monitor, and this stand (which was inexpensive relative to the cost of the monitor) was a great purchase. The base of the stand is a little bulky/high, and the soft material on the bottom of it can rub off very easily if you let the stand catch the back edge of your desk. Otherwise though, the stand is extremely easy to install, and it provides far more degrees of freedom for rotation and translation than the original stand for my monitor. Now my monitor is sitting at a comfortable viewing angle closer to my desk tilted slightly upwards toward me. Just keep in mind that you have to tighten down the height and tilt adjustments (the things that would be affected by gravity). So, if you want to adjust those frequently, this stand might not be a great fit for you. That said, it does provide a hidden but easy-to-access spot to store the keys needed to loosen it up to make those adjustments. So, if you need to make those adjustments, you'll always have quick access to the necessary tools. Highly recommended for its price in particular.

    A Solid Monitor Stand
    Size: Single, Style: Free-Standing
    This is an extremely sturdy monitor stand. Easily assembled in less than 20 minutes. Instructions were simple. The hex tools came with the stand, but you just need a Nr 2 Phillips Screwdriver for the bolts mounting the VESA plate to the monitor. Take note that this stand has a heavy base to hold larger/heavier monitors up to 22 lbs, but does not take a lot of space. I chose this variant so that it could handle my heavy 24-inch Planar monitor. The included cable management clip was a nice touch. Rotation and tilt feature moves easily and has decent range. I'm very happy with my purchase and it was available for overnight shipment in my region.
