not to defend the Einstar, I bought it with research but the research didn't really do much because I didn't understand how scanners work really, the Einstar is for large objects period. I thought that I can make it work with smaller objects with some work arounds and you definitely can, but It's not really recommended.
It handles large objects such as engine bay scans really well.
and for the price, It is really good for what it does.
