Solar panel would be most of the power. Guess they realized the real physics, but they still had to pump out some sort of rubbish in an attempt to satisfy backers.
Does anyone recall the original IndieGoGo campaign price? Was it a great deal cheaper? Was it worth the risk to save a few bucks (if any)? Has anyone tried the Android or iOS software and how good are the notifications?
I paid 159 usd for the black-ops in the original campaign

. Worth it? nope. It's a regular watch with stopwatch and some "energy metering" features. app (android) was terrible last time I checked and no notifications (apparently the 'X' has that)
