I have had extremely bad experiences ordering anything from China from a non-reputable company. Once I got a shipment of used batteries weighing the same amount as a pair of shoes for example. I think that's HUGE deterrent for most. Also the guru is proven, the interface is clean, the website is refined, and they offer adapters making it "seemingly" easier to integrate into any smoker. The other thing that's huge to me is wifi and application support. I'm not sure what you offer there but I'm sure it's going to be lacking compared to all the apps etc offered by developers who already have the guru and other units.
