Both my original "black can" neu 1515's have served me wonderfully for the last two years, got em up to 200F a few times with no worries, just trying to push em to the limit in 105F oklahoma summer heat lmao, i finally made the MMM fan come on!!!! for like 10secs lmao. But if mine is not as well suited to a car than the castle copy then it should be a good one, if one of my neu's ever goes out(god forbid!!) i'll get either a castle or tekno neu, until the T8 has been tested by the consumers throughly then i'll stick with Neu and its copies.
