Pluses:
- price
- average consumption ~200 ml /ho only at 1 level (from 10)
- robust construction but easy to use, to move
Minuses:
- i wish it had less heat than the one in level 1 for a small tent (9 m3) and 7 Celsius in exterior, but not exist this posibility; exist only one tuning used for power of pump and for air power simultaneously; i suggest to made one with 2 kw portable, i hope this will give less heat at minim level.
- more heat is dissipated by exhaust, needs to be improved for less consumtion and to be environmentally friendly
- pump noise
- transport cost
