Using it since June 2012, just finish 10-20%. I think can last 2 years for my daily used. I put NT8000(195/55/15 - RM175) at Myvi & NT5000(215/50/17 - RM220) at MPV. I like it comfort compare with my previous Goodyear GSD3, Bridgestone RE001 & Federal. Nearly as comfort as my previous Pirelli P7000(very comfort & grippy but not long lasting like CSC3/5). Grip as good as GSD3 or may be better. Anyway I'm not racing type driver just some time if rushing driving MPV at 180+kmh normally at night before AES installed.
