In reply to Tworule:
I've had the opposite experience to be honest. I've had a pair of Aku Utah Micro for about 6 years that have done me proud for UK hillwalking, 4000m in the alps, even a bit of vertical ice. Re-soled once (badly by the cheshire shoe people but thats another story) and maybe reaching the end of their tether now after some serious abuse.
I've contacted the UK distributor about which boot in their current range best matched the utah and they were pretty friendly and helpful. Never had to actually use any customer service though in terms of repair or replacement so can't comment there.
