looks great
Flame effect is real and not cheesy
2 steps actually adjustable (remeasured by Stromverbrauchsmeßgerät)
light, small and portable
(O / -)
is just a fan heater and so loud but audible (my TV has made louder by 3-4 stages)
because of the size takes little space heating (yes, there are also the "not mini" version)
