Query: Great product. One Flaw

I liked the size & price of this product. It fits a full sized keyboard & mouse/trackball with relative ease. The wrist rest was a nice surprise. It's not as cheap as I thought it might end up being. The mouse pad however, is. Though that's not my gripe with this thing. As I said before, it's nice & big. Seems to attach to the underside of a desk rather sturdily also. The left & right swivels are nice & make things convenient. The tilt works nice, the lock to control it works nice as well. it slides in to tuck away completely, as long as you install it far enough back. This thing is wide & can be very long when pulled out completely. All good traits in my book. The only downside to this product is that it hinges all it's support in the middle of the tray, making the platform quite wobbly. It doesn't feel weak or unstable, just wobbly. Other than that, it's a fantastic product for the price. If I could give it 4 & a half stars I would.
