Wiber, all inclusive Spanish car hire

[Desiderata]

Has anyone used this "all inclusive" car hire service?
Seems like a good system to bypass all the usual holiday car hire woes. You "check-in" before you go, all insurance, damage waivers etc are paid up front and they send you a unique bar code which you scan on arrival at the airport and it opens up a little keybox and off you drive. No queues, no inspections, and the same when you return the car, just drop the keys back in the box and off you fly
Doesn't seem too expensive for what it is, I'm getting a Focus (or equivalent) for £350 for a week in Southern Spain. If that's genuinely all I'll get hit with and the process works as it's supposed to, I'll be happy.

Yes, used them in Palma a few years ago. All very convenient, I think you have to take out the full insurance to get the quick service you describe, but that was fine.

Only thing there was that they were a short bus ride from the airport.
