Thank you very much! I will keep learning from this forum. We also can offer pickup or UPS fast delivery service from US warehouseI'm sorry for your situation, but I feel compelled to observe that you chose to return to a marketplace you knew supported fraud, and roll the dice on an untested vendor. If we all just refused to do this, Chinese vendors would learn that a reputation for honesty supports higher prices.
One of the major benefits of this forum for me is the shared experiences. Ditto for Will's videos. Amy Zheng at Docan is an example of a Chinese rep who has learned through years of experience that honesty and product support build brand credibility which has real value in the US market. She follows the forum and communicates through it; she recently posted this acknowledgment of what she's learned through interacting with us.
Old proverb: "A smart man learns from his mistakes. A wise man learns from the mistakes of others."
Right now, like it or not, all the LiFePo4 products come from China. Disreputable Chinese companies (and entire marketplaces) figure they have us by the 'nads. Happily, a few seem to have figured out that having a trusted brand is good for business. Let's look for those, call them out publicly here, and support them.
