I pulled it out this week to check tracking force after a little modding of VTA and the damn thing was dead, even after the required 24 hour charge up. OK, no surprise, time for a new battery (confirmed by a read of the not so well-written manual). Unfortunately, the battery is not user-replaceable and the manual instructed me to contact the US Distributor for further assistance. No slam on the responsive Bill from AudioFeil but what I learned was that this gauge has to be sent back to the UK for battery replacement and 'updating' at a cost of $140 plus shipping to England. Yes, this is a gauge we are speaking of and an almost perfectly functioning one, albeit with a dead battery.
It may be true that the resulting modified gauge would contain a new battery pack that in future I could replace myself, but I find myself wondering why any digital gauge for measuring stylus tracking force would require this amount of work and cost when relatively accurate digital stylus gauges
