The manufacturer's video makes it look like it might be a little wobbly or flimsy, and I mostly expected I'd send it back. The opposite is true, and I could not be more satisfied. The design is excellent and uses very high quality parts and construction. Seems like it will last a long time, even without tender loving care.Installed simply and effortlessly in my Toyota, using the original seat bolt and a very small cylindrical thingy. Took about five minutes, including the time to track down my socket wrench. There are also three additional just-as-simple installation adapters that seem like they'd work with most any vehicle configuration imaginable.It's almost infinitely adjustable, so getting it optimally dialed in for my computer took a minute or two, but once you lock things in, they will not move. It swivels, tilts, rotates ad telescopes in multiple axes, so it can be fairly short or very tall. The computer sits very securely, but can slide out instantly, without loosening, unscrewing, or undoing anything. It also works with my iPad.If necessary, it can be completely removed quickly (flip one lever) and re-installed easily (same lever), and it folds down (somewhat) compactly.More expensive than several others, but I got a great deal on mine in a flash sale. I'd be just as pleased if I'd paid full price, based on the quality, simplicity, adjustability, and stability.Recommended.
