As far as we know,most of the clients when they buy products just know to compare the cost who is the cheapest one, then choose the cheapest as their supplier. These Customers just to compare the prices, but never to consider the continue support service.
And many of clients when they meet the equipment's problem, they was found that he can't get their supplier no longer, or their supplier need them to pay the high cost for the continue service, or their supplier never have the after-sales service.
I receive many clients help require come from different countries, but I and my support site only support to my clients. If all the clients who bought cheap price from other supplier and want to get support form me. I just can say I'm not your equipments factories or supplier, I can't provide this service. Also I have not so many time and have not so much energy to do this support.
So I hope all the clients can find the correct equipment brands, and the their correct supplier who can give you all the continue support.
