@vespalien@SangitaMyska@London_Centric Yes it is. Any time before the first 4 hours is up, it can be redocked then taken out again. You get a text to tell you your free time is running out.
@BenClaimant They've been there for well over a year to my knowledge, so hardly new news.
You get texts to say that your free 4 hours is running out, you can redock and get another 4 hours free.
