I've watched lots of bad videos on these heaters yet gave it a try and I'm glad I did. Before I received the unit I bought all the things the other you tubers said I will need to upgrade. Pretty much a waste of money. The only thing I had to add was a fuel filter. The fuel pumps that made a ticking noise were taken care of and the fuel lines are different, much stronger. This heater is almost silent and everything worked very well right out of the box. Definitely worth it if you ask me. The heat is crazy hot too. Make sure you burn them on high now and then so you don't get a build up of soot
