Anybody advise against getting this camera?

If you don't mind having to use their proprietary apps to dewarp the image, and Internet Explorer with an activex plugin to manage the camera, then it will probably work fine. I have considered buying similar Chinese fisheye cams in the past but I really don't need one so I never made a purchase.
 
I highly doubt many people here will advise getting one of these.

Is there are reason you are going for a fisheye camera? Even the good ones aren't that good. And this isn't one of them.
 
Chinese products are all hit and miss. Sometimes the plugins can be such a hassle to deal with. Buy at your own risk pretty much.
 
If you do buy, just expect the worse. So when you do get it, you won't be surprised.

I personally wouldn't as I don't like burning money.
