Don't sweat it! People are allowed to have their own opinions lol, you have to go with what you think is right for you, not what I or anyone else say, just try to see through our conflicts and pull the info you need.
I have used a LOT of Chauvet products, and I tend to baby ALL of my equipment, and have not had any major problems with any products I've purchased from any brand, be it Chauvet, American DJ, Martin, Eliminator, etc, I've bought from most established companies, regardless of others reviews. That being said, I've never purchased from Blizzard, but most likely will, just to try them out.
In my opinion, from what I've seen in the Chauvet Geyser, it'd be a great product if used properly.
Blizzard hasn't even released photo/video of their similar effect yet, so I can't really compare.
Now I just have to buy both, THANKS BILL! :P
