I don't expect anything without a replaceable battery to last over a year with daily use, if it does, that's a BIG plus. Take care of what you have as best you can, clean the connections and allow to fully discharge and re-charge once and a while, should be good to go. My biggest problem, I end up dropping everything at some point, and I'm pretty careful...it just happens. The way I look at it....If I'm not spending $7-10 a day on analogs, I can afford a $20 battery konking out every 3-12 months. I've come to realize that these things won't last forever, they're relatively inexpensive electronics that I use many, many times every single day....You buy a Rolex, it'll last a lifetime...but I guarantee it'll see it's fair share of time in the watch repair shop. A Rolex is worth repairing, an inexpensive e-cig...buy another one and move on.
