We Did put a neutral feedback on the Other faulty item we bought off them, which they Also told us we were using it incorrectly (despite the three videos we sent and despite the information provided in the listing), until finally admitting we were right and offering us a refund.  Considering the overall way we've been treated both times I think 1 negative feedback is pretty warranted. 

Thanks guys.Appreciate the support. 

The video and info did not resolve the issue. It just showed and explained that the lamp would remain upright If used at certain angles. They also did not initially offer me a refund. After posting the review they resent the same video and info until they later finally admitted that we were correct and the listing was unclear. 

Thank you for the info.I'll contact TradeMe tomorrow morning.
