Few Watts, little pressure and amount of smoke... That is, for a 50 sqm shop with ventilation, don't expect the smoke to last long in the space (2-3 minutes intensely and another 2 minutes just barely, as if someone smoked 1 cigarette). In short, it doesn't last long... you need to keep using it if you want to have the smoke effect...
For its price, it's just right... if you want it for a house party, it will do its job, but for professional purposes, don't expect miracles.

Update after 2.5 months at most...
It started to produce almost no smoke and it seems like the liquid is burning inside the nozzle, and instead of smelling nice (I used vanilla scent from the same company), it started to smell like burnt plastic and iron together... also, it produces almost nothing, it's completely clogged... Without any excessive use...

I have used it in small spaces of about 30-35 square meters for photography and video. It is more than enough for my needs. It has not presented any problems for me.

In an indoor space, it creates chaos, in an outdoor space with very little air for the photoshoot.... it is a relatively good add-on
