Better than expected.
I purchased this from Adorama website and use with 70-200mm. In my case, it gives me up to 400mm reach and it is great to shoot the subject far away. I read some reviews before, but this extender is better than I expected. However, it does not allow you to use AF, and you need to practice with manual focus. I will practice more and hope to have more great shots for my grandchildren's playing sports.

Great extension
I use this 2x with Canon 300mm f/2.8. There is no noticeable depreciation in the image quality after crop and the AF speed is still reasonably good.

Just More Practical
The economy is what the economy is.
I traded a tele-zoom lens that I wasn't often using. Adorama was most helpful.
However, I missed the extra reach of a 400 or 500 lens for the fun stuff like shooting the moon. Mounted to a Canon 70-200, this extender gives just the extra reach I need for occasional shots. Mounted on a tripod, and attached to another Canon lens, this was a perfect option.

Works with all the caveats that you hear
Yes this does soften things a bit like you've probably read,, but the extra reach is worth it. I used it indoors for a swim meet. Had to use a tripod and push the ISO but it worked wonderfully.
For any tripod work or outdoor in good lighting you'll get good results. You'll lose a bit of contrast but nothing that isn't fixable. It's not a replacement for a real 400mm lens vs a 70-200 f/2.8, but for the price you can't beat it.
The question is whether or not you really care about all that minutiae. I don't. Contrast and softness for my intended uses are a non-issue. I wouldn't use this, for example, for portraits, but that's silly. Use it for some situations where it makes sense and you won't be disappointed.
