Order arrived well packed and in good condition. I received the updated V2.1S controller board with firmware 2.10, which has the fix for the battery drain issue some of the previous versions had.

Build quality is good, but as noted by numerous reviewers, it suffers from a safety point of view. The case is not grounded, and there are some clearance issues with the AC/DC coupling with one of the power supply radiators.

You can find on Youtube detailed tear-down and modification videos which explain how to make it a safer station.

BEWARE! This is NOT the 2.1s hardware revision. It is the 2.01 hw revision with a FAKE FIRMWARE flashed on it. This is a picture of the 2.1s hw version of the board taken from Banngood's own site. There are many youtube reviews detailing the differences between the models. The 2.01 version heats up more slowly but if it is running the later software may pose safety concerns. If you want the 2.01 version, you can get it cheaper on this site or from DX. I consider that I have been defrauded but Banggood have refused to offer a full refund after over 1 month of trying. The stars for this product are irrelevant as Banggood will not allow 1 star reveiws.
