Eyeup Ray and Christine. No, fortunately never had to use it, although it looked good
Long since removed again (and recently consigned it for proper disposal via ATS Tyres) - but at the time, it seemed to be the best of a bad bunch of "solutions". Spare wheel space taken up by toroid LPG tank, and Tyreseal was difficult to get washed out by most garages/tyre factors, so rather than write off punctured tyres that way, I would perhaps have had to
very gingerly try the space saver for a mile or three, if the need had arisen.
Since then, several changes:
1.) Have joined Caravan Club's Mayday recovery scheme run by Green Flag, who guarantee to always recover to a garage by low loader - in the UK, anyway.
2.) Discovered that any branch of National Tyres
will wash out Tyreseal from repairable tyres - joint promo deal with Tyreseal.
3.) Still don't use after the event Tyreseal though. Have now very successfully used Puncturesafe (Ultraseal derivative) permanent install puncture sealant, and mainly rely on that. At the time I hung the space saver on the back in desperation, I had previously tried Seal-a-Wheel, which had been useless - heavy unbalanced wheel vibrations at 55 mph plus (others have reported the same), and had had to get it washed out. No such problems with Punturesafe - also used by a number of big mixed fleet operators, including Royal Mail. It even runs vibration free straight after long periods with the Bongo unused - which ours has suffered several times while I recovered from surgery recently.

do you mean you actually use the space saver
