loribear Posted November 15, 2012 Share Posted November 15, 2012 good evening everyone, hope your all well & taking your echinacea i just wanted to ask a little question , i was emptying my suitcase making room for the chrissy presents, & found a carbonmonoxide tester, it's one of those small stick on types, i always take one on holiday just in case, but have never seen them change colour, i'm glad to say, but was wondering what you thought about them ? do you think they really work or do you think the battery ones are better,& do any of you actually take these on board with you ? lori Quote Link to comment Share on other sites More sharing options...
