I bought this product 15 days ago and I find that positioning quality / price is not bad at all. it cost me 178 euros new. the system is simple: a normal smoke machine but the smoke goes through a tray that you fill with glaons, she is responsible for ice particles and falls to the ground a few seconds / minutes instead of climbing!
This machine is great for small spaces or small scenes on the other hand if you have more surface area there is a model + in the same brand EUROLITE NB 100 if there is "BOOST" is that makes these machines (+ / -375 euros), Antares (+ / -700 euros), and we move on to models APRS "pro" MARTIN etc. .. prices unaffordable for an individual!
It takes a few minutes between each puff of smoke to allow "re-heat the mill"
