a quick look at the Quantum and how the machine works. This is a direct competitor of Rainbow, Hyla, Sirena and was completely marketed online. They now have an upright version of this..and I do believe that they have discontinued this canister model and shifting to just the more compact upright unit. For the money it is a good machine. It's a lot cheaper than what you will spend on other units but the build quality represents this. This in my opinion will fall under then "chunk it when it Breaks" category. You get what you pay for! Customer services was phenomenal when I had to purchase to replacement clips for the water basin. Amazing communication online and a quick phone call with a courteous rep and my parts were on the way! Thanks for watching!
