If you ever have a problem with a product that you receive from these people be prepared for a long (and pointless) exchange with a barely-literate Chinese rep. They will reply to your emails exactly ONCE each day with the stupidest and nonsensical replies you've ever seen. Broken or non-working product received? "Please upload a video to Dropbox of the product showing what it is doing". Once you upload the video of the product 'not working' they will have a 'technician' review it and make suggestions. "Can you please shake the product?" "Please replace the battery and try again". Even if none of these things apply to the product you bought.
Once you have jumped through all of these hoops and they are totally convinced that they sent you a defective product, they will ask you to pay some additional amount of money to get it replaced. Ridiculous company.
