Mr2 Heaven are not liked by many vendors, reputation as the home guys who give it a go, and end quality is usually a little off Oem, perfection, what you might think you are buying.
I have bought their reproduction gear shift and the finish is not as good as their images. Their response to complaints is they are individually hand finished so variants to finish is part of it. I would not have bought if they showed the end product I received (done my money, as cost of shipping back and cost of shipping here is counterproductive to getting the item price refunded).
Other publicised fails of recent years was the initial carbon fibre intercooler pipes that fell apart (said to be corrected in a changed manufacturing / design), trims that didn't fit well (possibly install or product), and all sorts of near or complete misses of product. With all that said, they made reproduction clam shells for steering wheel and buyers seemed to be very happy.
They develop their own parts and sell others home made parts from other enthusiasts through their website.
Mr2 Heaven has been relatively good in fixing / replacing major issue items to local (USA) buyers.
They sell a lot of products with many happy customers, and many customers of past that feel ripped off, kinda like Racer-x customers. I think it's great what they do for the community, as there is no other companies giving it a go for a small target market.
