This is not a serious lens -it is a toy. Keeping that in mind, it is a decent toy and it works reasonably well for the price. It is rather difficult to focus accurately, but I've got the hang of it after some practice. Like all cheap lenses, it suffers from some purple fringe. This type of lens is much better than the shorter and lighter 500mm mirror lenses that cost about the same. The 2x converter is very cheap, single-element; with it, the lens becomes very difficult to focus and to keep steady enough to avoid blur. Except in the brightest of bright sunlight, you can't shoot with this lens without a tripod. The tripod mount looks good in pictures but it's a joke: it's made of plastic, and it's way too flimsy to keep the lens and camera stable. Just breathing on the camera makes it sway visibly. Mounting the camera on the tripod works much better, and the lens is not that heavy. Note that the 2x adapter works with this lens only -you can't use it with another lens. The lens has its own threaded mount but comes with a Canon EF adapter; the 2x adapter goes between the lens proper and the EF adapter.
If you want a 500mm lens and can spend a little more money, try a 75-300mm zoom (I have one from Canon, which is ok but not great; I hear that Sigma and Tamron make decent zoom lenses in that range) with a 2x multiplier (get a 7-element rather than a slightly cheaper 4-element one).
