Jining Luma Machinery Co., Ltd Jining Luma Machinery Co., Ltd. sent defective units and not provide refund
I have purchased from this company 2 devices. Both arrived defective.
Requested a refund, just to be told these devices were a "sample" and they do not represent how items would actually be. I have paid top dollar for these devices and have not been provided support, refund or any cancellation.
Beware of this company, they will ship to you bad products and charge you like they are new ones.
