Should I just buy the cheapest PS3 Eye camera from ebay and see whether I get the flat lens or round lens, and proceed accordingly?

Its a real hassle to determine if its a flat or round lens from the photos people upload on ebay, as they’re not very good quality.

Edit: I found a really cheap one on ebay which was at auction and got the highest bid (it was a little over 4 euro with another 4 shipping, so honestly not bad at all). When it arrives I’ll try out the steps in the video and report back here I guess. Hopefully it can help people when buying these cameras to not struggle looking for the rounded lenses and worry that if they dont get that one they cant do their project.
