Start my business satellite tracking service with the company Bofan China , want to tell my experience , so others will be able to avoid this company and choosing any company to take the guards .
First buy the model PT302 , and use the platform of them paying a license , soon began to fail trackers , a purchase of 50 trackers , today I have 40 bad , I had to buy the new model took PT500 , also began to fail, I have like 10 bad 30 units purchased, they also buy PT200 and PT30 alike were the last to buy PT502 and PT600 are a little better, but we are starting to fail.
With regard to your software, the visual interface is good, but when I had the service using their server on several occasions worked very slow and the server was falling , leaving without service for several hours to fix , I buy the software and enable my server, after a year , they would not give me ANY technical assistance from yesterday with the completion of the API v2 , the software became obsolete , I went back to ask for help to keep the money invested and again refused to give information or assistance technique.
If you want to verify what I am making , I can send you pictures of all that I have bad trackers .

The company lost money this is a lot, and are not responsible for its products.

My advice, look for companies with good support, even when you pay a little more, because at least Bofan, sooner or later lose their money.
