When I buy a gadget, I expect it to work as advertised. This sets me up for a lot of disappointment. Inaccurate GPS trackers, counterintuitive interfaces, and鈥攎ost frustrating of all鈥batteries that die well before they鈥檙e supposed to leave me forlorn.
Thus聽it was with much trepidation that I decided to try the 聽($299). The solar-powered activity monitor launched on last September with a simple promise: never worry about battery life again. But could a small startup crack the all-day-use problems that still plague giants like Apple and Samsung?
In bright, sunshiny New Mexico, where I live, the answer is yes.
The watch needs only an hour of daily light exposure to go on working forever鈥攁nd the company says artificial indoor light works just as well as the sun. Now, don鈥檛 expect the Lunar to replace your training watch just yet. There鈥檚 no heart-rate monitor, and in place of a display, a pair of hands tick around a face behind a transparent solar panel. Vibrations alert you to texts and calls on your synced phone, while an LED array flashes when you hit activity targets. But for the convenience of never having to charge again, I鈥檒l take it.
