Borgenson box better?

So I had installed one of the new Borgenson boxes back in late May. Love the fast ratio and tight feel. I thought it was great or so I thought till it developed a leak at the main shaft. Well, I had to send it back to Borgenson and after 2 weeks had gotten it back from them (shipping paid for by them) with a new shaft seal installed. After running my car at the carlisle autocross 2 weeks ago and some around town driving the new seal seems to be holding up great. Long story short, if you plan on installing one of their units their warranty repair seems to be pretty good, and yeah, I'd buy another one if I build another car.
