Arrived with none working properly if at all, seller wanted me to return the item at my cost but I couldn't because postage costs would be half the cost of the item thanks to Australia Post. Seller insisted I return the item and said it was "impossible" none worked because they sold a lot and even insinuated the video I sent of it not working was my laser and not theirs. I even proposed a partial refund and they refused, and they then proposed a partial refund AND sending the items back! how insulting! steer clear of this item and the seller, awful service and even worse product!
