He asked us to provide 1800gs and 2500gs center gauss magnets for him, and when he received all, he found 1800gs can't be used for his equipment, then he asked to return 1800gs fee to him, we refused and told him this is his requirement, Due to he couldn't achieve his goal, he wrote this fake comment. I told this client before production that the center gauss value is 1800gs and 2500gs, and measured the magnets before delivery and marked the result on the package. This client use a gauss meter with large error (this model always has 1000-1500gs tolerance than other models of gauss meter, if you don't belive, you can ask us to show the video for the testing result of different meters, I also showed the video to this client). If it is a bulk order, we usually refund this fee. But using such despicable means to extort is wrong. I hope everyone can have a good trade environment
