  • I Reccomend It, Good Product, For Price.
    Verified Purchase

    Love this! my only warning is that if your space you are putting thin on is open ended, you may want to pit something over the side(s) of it, because it looks like an afterthought, if not. I actually took a piece of cardboard, and covered it with lack contact paper and stuck it to the side, to make it look more solid state, rather that the add-on that it is.

    Sturdy and comfortable for wrists. Only complaint is the edges are a little rough and has damaged my chair arms where it rubs.

  • Great keyboard and mouse tray.
    Verified Purchase

    We bought a desk from our local architectural salvage and needed a keyboard and mouse tray. This did the trick and is working well.

  • Useful Product
    Verified Purchase

    I received the product and the package was missing a part that is essential to its function. Overstock attempted to obtain just the missing part but was not able to do so withing a reasonable time frame and decided to send me a whole new product which works fine as all of the parts were in the package. I really appreciate the effort that Overstock went to to make me happy. The product would be much improved if it came with a built in mouse platform and I would have been happy to pay more for the product with this additional feature.

  • missing screws
    Verified Purchase

    Just a little upset that the screws needed to install were not included. I've never received anything that required hardware that didn't come with the hardware that is needed. Still haven't installed it!
