While there's some debate about how many hours a phonograph cartridge stylus lasts and how often it should be replaced, one thing's for sure: not keeping track of your cartridge's "mileage" makes difficult knowing when the time's come for a re-tip or replacement.
The just introduced StylusTimer aims to make it easy to know precisely how many hours your stylus has put in

Turntable phono cartridges have a stylus (needle) that should be replaced after every 1,000 hours of use, sometimes even sooner, depending on the cartridge. A worn stylus degrades sound quality and can damage your valuable record collection. Unfortunately, most turntable owners have no idea how much time is actually on their stylus, especially as the months and years go by.

Now you can track your stylus usage easily and precisely- with StylusTimer! StylusTimer (US and International patents pending) is a unique chronograph designed for use with turntables.

 StylusTimer is a must-have accessory for all vinyl lovers and turntable users.
