Minihobby Models (MHM) pirated the Tamiya Enterprise in 1:350 scale.
MHM was part of the greater Wasan Moulding Co of China who is also the parent of Trumpeter. MHM acquired the reputation for ripping off other manufacturer's products. Their quality was generally less than the original. Engraved detail lines were deeper, raised lines were higher, surface detail generally not as crisp. At several sites I've seen MHM is now out of business [but they could raise their head again at any time].
I attempted several MHM kits which were relegated to the circular file due to the effort required to bring them to the standard of the parent kit from which they were pirated.
Remember to consider the cost of your time whenever you go for an off brand manufacturer. The money you save up front is spent fixing the basic deficiencies of the kit.
