A sufficient amount of tobacco in each application. Sometimes it gets stuck even though the indicator shows that it is ready for use and doesn't come out. For its price, it is worth it anyway.

Perfect for its price!!

It takes a little while to "warm up" if you press it for a long time, but if you find its rhythm, the result will reward you!
It is a bit weak for outdoor use, but it did a great job in an indoor space of about 180 square meters with the green liquid!

If I were to buy it again, I would spend a little more money to get the model with the built-in LEDs.

Update after 2 years of mild use:
The foot switch has broken, specifically the cable has been cut internally, but as a device, it still works. It is better to prefer a wireless option, which is a safer choice.

It is very good for its price and for a small indoor party.
I did put sparse smoke and not dense, because people would explode indoors, it also takes fragrances in the smoke.
I don't know if it's from the store where I bought it, but it also has a wireless remote control in the package to activate it remotely, although it has enough cable on the smoke switch.
It is good not to leave the liquids inside for more than a month and to finish them.
Then fill it with deionized water (like the one they put in car refrigerators and steam irons/presses) It takes 500ml and from what the seller told me it can release for 20 to 30 minutes (I didn't try it, he wouldn't mean continuously) anyway it will give you enough time if you don't drink its blood and step on it every time it's ready to release, because I see you in some emergency room with a breathing problem.
I don't think you'll need to refill it during a party, we're always talking about a small space, I believe even outside in a small courtyard it will do the job.
