Accurate, but a two-year life - battery cannot be replaced.
December 5, 2015
I had the Swammi and it worked well for the first couple of years. It was easy to use and had all the local courses I play. It is a decent value. However, it has a life of @ 2-3 years. After that, the battery no longer takes a charge & it CANNOT be replaced. You may want to consider paying more up front for a product that has a longer life and replaceable battery.
Pros:Easy to use, accurate, compact, and has most available courses.
Cons:Lifespan of product is limited with a hard-wired battery that cannot be replaced once it stops taking a charge.
