Combined smoke / carbon monoxide detector

Whittakerr

The smoke alarm in my caravan recently must have gone faulty, it went off, as usual, when making some toast, but no matter what I did I couldn’t reset, anyway I’ve thrown it away now.

I want a replacement and I am considering a combined smoke / carbon monoxide detector. Has anybody got any experience of these in a caravan, and if so would you recommend one for use in a caravan.

Thanks.
