I just received mine today, still waiting the adapter from fotodiox but already did some handheld tests
its bigger than I thought

First, the magnification it gives: full zoom without and with the TC
Image

Image

I noticed the focus tends to hunt more with the TC on, if focusing the bird instead of branches was hard, with the TC it will be even harder, gotta try it in the field
Also, didnt noticed loss of light and the DOF got smaller, which is cool

Now IQ wise, I had some surprises
here is a 100% crop with the TC vs upsized image

Image

Where did the red fringe go? shouldnt the TC magnify it as well?? I was expecting more artefacts, not less... I must have gotten a miraculous TC...
About the IQ, id say only pixel peepers would notice the diferrence in this comparision... at least while using low ISO an upsized must be pretty close to the TC, I used ISO200 on this test, it looks bad cause the noise is also upsized

100% crops without and with the TC
Image

Image

Again! The TC shot doesnt have the red fringe that the first picture has
also it shows a lot more of crisp texture on the box

Well Im happy with it :D

Looks like the TC has some blue-ish fringing opposed to the standard red fringe. Looks good :)
