Home Cycle Lockers

(I never quite understood the way this works, I just want to ask a question, there's no issue)

Does anyone have any experience of the various "Cycle Locker" type storage you can buy? I'm fed up with juggling cars and bikes, so I think it's time my bikes had a separate place to reside, and a secure locker or two would seem to fit the bill.

Something like these:

I'm looking at commercial-strength stuff as I doubt anything less will be secure enough.

I'm looking for anyone who's bought them or used them, or similar. Is there anything I need to know before I order?

thanks
