There's a reason they are warrantied for 2 years. That is their expected life. I wouldn't call them junk. I would call them a poor choice. There are simply better options out there. Vortex, can-fan, and s&p. There's just no reason to use a no name china unit backed with a short warranty. Vortex is made in Canada. Can-fan in Germany, and S&P in America. I believe in buying quality products and supporting companies that make quality products. I truly don't care where a product is made, but the bottom line is Canada, America, and Germany pay their workers substantially more than China. The end result is a higher quality product that leaves the factory. In a nutshell you get what you pay for.
