Richard C.wrote a review of Suunto Battery Kit for 1st Gen. Vector, X-Lander, Altimax, Advizor, Yachtsman on May 29, 2010
I've had my Suunto Vector since about 2000. It works fine, and I wear it daily. You do have to replace the batteries every 3-4 years, though. That seems reasonable to me, and the kit is easy to use.
