As a dropshipper, I bought about 15 items from them.
In most of them there were shipping problems.
Some items did not arrive at all, some were sent up to two weeks after they told me it was shipped. Once I've ordered from their UK warehouse and it was sent from China.
They never took responsibility for their mistakes (mistakes? More like fraud).
Take it from a very experienced buyer and seller -
KEEP AWAY FROM BANGGOOD!
