My Tiny Tach recently died after nine years in service. The hours still showed but it wouldn't read RPM anymore, so I didn't think it was the non-replacable battery (actually it is replacable, but requires a little bit of cutting and soldering). So I sent it back to Tiny Tach for maintenance and they sent me a new one for free. Not even postage was charged.
Beware the ENM which looks like the Tiny Tach. I bought one because it had a maintenance interval timer included in it but it read several hundred RPM low at low RPM and more than a thousand low at high RPM. The eBay seller I ordered it from gave me a refund. The new Tiny Tach is working just like the old one and will surely last for another nine years. The Tiny Tach has always matched exactly the RPM readout on my Dyna Vibe prop balancer. Great product.
