I have had an MSR dragonfly for several years now and have always been really impressed with it. I have serviced it annually and kept it in good condition and cleaned it when needed. However over the last few months it seems like it just doesnt burn red hot in the same way as it once did. When I first got it Im sure that the entire burner cup glowed red hot. However over the last few years that doesnt really happen and more recently it seems that it just doesnt glow even slightly. It still boils and works effectively though, but just doesnt seem as red hot and efficient as it once was.

Does anyone have any similar experiences with the dragonfly and any ideas on how to sort it out? Have there been any updates to the dragonfly to make it any better? Do I have an old one??

Thanks
