No not in this case.
I am open to group buys, sometimes. But as a group buy would be carried out on the forums, Mp3Car would be basically suggesting that this product is suitable for purchase. This product is a risk.
I you can collect with others somewhere else, and do a group buy, go for it. But please do not do this on the forums. Support should be considered a part of product quality, and in this case, I think the lack of support completely erodes whatever physical qualities there might be.
