Bought a Tecware Titan chassis last month from them. Item received quite late using COD by TQBin, got it after 10 days. Don't know what happen but item stuck at prep for shipping quite long time.
The most unfortunate thing is there's no method to contact them, try googling them but got zero result. Worried if i got scammed, dont know what to do so i just wait patiently.
Then after check again item status changed to in shipment. Although with all the hassle, but I'm satisfied enough because item received in good condition and great product too.
Maybe you can try buying from them.
