1st: it only smells like chocolate in the bottle..... not while its smoking. It is definatly fully exchanged with my old fluid. I have been smoking out the house everyday this week waiting for the chocolate scent.
2nd: after 2 laps of my ceiling layout its done and needs a refill. 3 laps on my garden. 12x25 and 6x18.
3rd. Its messy on my locos. It gives the signs of being overfilled by covering my locos in raw fluid.
4th: my mth fluid outsmokes it by far. Its not even a comparison.
I have experimented with diferent amiunts of fluid and letting it soak for 20 minutes before use. It makes no diference. Ive tried as few as 5 drops up to 20 drops with no difference. I have only ever used mth scented fluid and a brand called supersmoke. Both perform the same with long lasting, thick plumes of smoke. The jts is a more thinner, lighter appearing smoke based on how it hangs above the loco and gets carried by the passing train. I must say, this is my 1st truly disapointing train purchase.
