In the foreword I would like to say that this adapter does what it is intended for. It holds your laptop or monitor and keyboard at different heights and different angles, effectively turning your regular sitting desk into a standing desk. On the other hand, there is absolutely no way to raise or lower platforms while they are in place. holds no weight at all. Each joint is individually adjustable, requiring both hands to work on a joint. Also, the hinges themselves are plastic, and it's not clear what the retaining tabs inside are made of. Since there's no structural support at the back of the main platform, I'd be wary of the official 13-pound limit listed in the product literature. This product does what it says on the tin but be aware that it does so with some caveats.
