As usual, Mitutoyo tools are very good in workmanship and finish, I have no problems with them. Minutes is too long and will shorten battery life. The LR44 battery type is alkaline and tends to leak when stored for a long time. The lithium type can be more modern and suitable. The suitcase arrived with broken hinges that needed to be repaired. I feel that for such a precise instrument, Mitutoyo should be able to find the best case that will fit. I have a much cheaper Kinchrome tool box with properly made hinges that will last for years.
