I usually do a search for reputation but mine was not thorough enough prior to purchasing from Chinavasion. Item I purchased was a portable projector and the native resolution was advertised as 854 x 480. Upon receiving the item, the native resolution was only 640 x 480!! The item had many scratches and showed symptoms of usage. The remote was squashed. When customer service responded to me, it took 3 days. I mentioned the problem and was asked how did I know what the true resolution was. They told me to prove it. I did in many ways, one the instruction manual mentioned native resolution was 640 x 480, it had VGA written on the device (VGA=640 x 480) and since it was a DLP, I contacted Texas Instruments. With everything proven, including pictures showing usage, I came to another conclusion. These projectors were dead stock and Chinavasion decided to exaggerate the specs to move the products. This is clearly fraud!!! When I mentioned this, they told me they didn't know as they just move the product from one end to the other for financial gain. In a normal state of mind, if you owned a business, wouldn't you thoroughly check the product you are going to sell before acquiring stock??? Because your business will be responsible for what you sell. Anyways, Chinavasion can't be that stupid and they knew exactly what they are doing. They wanted me to send back the item and would not reimburse shipping costs even though they are at fault. For a slap in the face, once the item is received, they said they would give me a refund MINUS the shipping fee I originally paid to have the item sent! Moral of the story: Chinavasion is a scam!!! Don't buy from them!!! They will rip you off!!! If you send back the item, they will pull the same trick on their next victim. So instead, file a claim with your credit card or with the payment method used. More people do this, Chinavasion will lose their credit card contracts as well as PayPal contracts.
