It is really good (compared to what we have in certified GA)
Most of unlicensed strips are dodgy for a standard SEP, but it is worth a look if there is no airfield near your destination.
This database is well used by the UL community. Each plate has the phone number of the owner who generally is welcoming (compared to what we have in certified GA, have I said that before ? 
).
I even know a guy who has his own strip but doesn’t want to be in this database because “then everybody would come”.
Unlike aerodromes in AIP, there is a mix of goodwill and badwill in those French ULM airfields ranging from “welcome, no Avgas but will go ship it, do you need some?” to “do I/you know you/me?” but for sure you will be gutted to see some that sits exactly right at the place you wanna go for but have 200m grass runway ;)
