I like the tone of Sweetones but have never mangaed to get one that is completely in tune with itself (usually the bottom D is a bit dodgey)... but the colours are pretty....

to tune to another instrument (also to clean it) the above advice is good.. loosen the mouthpiece with hot (not boiling) water...

I don't advise gluing it back on.. they are usually a snug fit anyway... in fact putting some vaseline (white petroleum jelly) around the end will make it move easier for re-tuning.
