I have tried this a couple of times over the years and decided to give it another whirl when I had really dry chapped lips recently.
First off, when you put it on it has a tingle that reminds me of Vicks Vapour Rub. It also does quite well in it's capacity as a lip protectant and has kept my lips feeling moisturized and protected in an air-conditioned building where other lip balms were just drying me out.
The packaging isn't sexy looking but the squeeze tube is quite good for hygiene.
I tend towards more natural lip balms as a personal preference, but after rediscovering this one, I will definitely keep it in mind for when all other lip balms have failed.
Carmex has been my absolute lifeline since discovering it in the states. I was one of those $2 shop lip gloss kids at intermediate, so my lips are pretty ruined from that even after all these years - constant chapping (amplified by inability to breathe through my nose). Carmex relieves this quickly, smells great, and makes my lips look plump and supple. Its great value as well and easy to find at chemists - though I stocked up in the States recently, hope my local gets the 3 packs in soon! I have one in my bag, one next to my bed and one next to the couch.... my Carmex is never far away!!
Tips: Don't squeeze hard, you don't need a lot! And don't leave in hot places as it will melt. It does re-form once cool, but will be extra runny if you use it while warm!
