In/Out Line Calling

I've seen some posts around here about the In/Out Line Calling System. Most are really old. Does anybody here have version 3 or 4? Does the battery last? Does it detect the court good during setup? Do shadows and low light affect court detection? Does it sometimes miss the call entirely? Is it reliable?

I can't believe the seller offers no returns nor trial periods. I really want to buy it, but with literally no warranty or guarantee, its too much of a risk. I'm not gonna spend $600 on something unreliable.

Thanks!

Before the lockdown is a long time ago. The new v4 should be different. They seem to mention the possibility of only getting net devices but the store always pushes the line sensors.

Yeah I was trying to get a trial for my tennis club but they never responded and with no warranty etc, many large facilities simply can't get the approval to bring it in. There are other solutions but they cost much more.
