野島 4 It’s extremely high quality. Mounting is not that easy as described in the DVD video, especially in snow storm on snowy terrain; I had to ask a tire shop for help, but they put it for 1000 yen.Driving it’s not fun, due to some trepidation but not that bad as others cheap brands; but safe and sure.It starts right away even on black ice, where even a four wheel drive car may fail.My car is FWD( FF) Isis Platana.I won’t suggest driving faster than 40 km/Hour . At 50 km/Hour trepidation is stronger; I fear some bolts will loosening on suspension joint, maybe not.But surely puts some extra pressure on shock absorbers. But it’s a must have for FWD cars in winter.
