Here's the first group buy thread:
Prinsu Roof Rack Group Buy No one in that thread ever reported receiving their racks. Of course, they may have reported elswehere, but it is not clear.
The group buy was closed after 4 days when, supposedly, 50 of us bought roof racks. I can only find 4 or 5 reports of members who installed Prinsu racks, and it's not even certain they were purchased as part of that first group buy. Here's one install that was posted up one day after the first group buy was announced:
Prinsu 200 Series Rack INSTALLED and that was not exactly a smooth install - required professional help in the end.
Perhaps it's just my (incorrect?) read of the situation, but the Prinsu rack does not appear to be receiving glowing reviews, the group buy sounds like a scam (where are the 50 who bought racks?) and I can not find one example of anyone who bought a rack from the first group buy, received it, installed it successfully and was happy with it. If anyone on here has that experience, then it would be very helpful to post it up.
So, to elaborate, as I said in the first group buy thread, Prinsu left a bad taste in my mouth by announcing a group buy and ending it in less than 4 days. That "bad taste" has not been removed by any members posting glowing praises about their group buy purchase experience and their satisfaction with the product.
So, since you asked, that's why I am not at all interested in Prinsu racks - too many other good options on the market.
