is it worth buying it?

ok my Fly 12 front camera has given up and my varia  515 is nearly at is end of life , battery on both devices have either given up or are about to give up, I defiantly don't want to spend nearly 400 Euro's on a new Fly12 at the moment but I don't want to ride without a Varia. I had hoped that both devices would manage until a improved version on the Varia 715 had been released but I guess I'm not that lucky.

I think , I can overlook most of the Varia 715 issues which seem to be many but would love to hear honest feedback on the lack of image stabilization, are people able to see the license plate numbers in case of close paths ?
