Tomtop Wholesale broken product, no support, restocking fees City of Industry California

I purchased a screen mirroring box through these guys on Newegg.com. The product came in broken out of the box. It had no instruction, and nothing to work with.  I used 5 different devices to test it, just to make sure I wasn't doing anything wrong and never got it to work.  After contacting TomTop, they emailed me something that looked like instructions (all chinglish), but still didn't offer any actual support or insight on the product or troubleshooting the product.  Finally, I decided to return the device, and had to pay my own return shipping.  After receiving it back, they deducted a restocking fee and claim that everything is working.  This place is a joke, save your money.
