Battery life inst an issue until you leave it on and its dead the next time you go to use it. And no matter how much we think we will always turn them off, reality is, we dont. The shake awake feature is a big help there, as at least it shuts itself off when its sitting in the safe. You just need to understand how that works too. As long as the sight sees movement of any kind, the dot is back on.
If you lke the SPARC, go for it. The only way youre going to know what these are about, is to jump in and start using it and figuring it out. They keep making new and better models every day, and this one wont likely be your last.
Now, since youre already sliding into the abyss, better duct tape your wallet shut right now! Hey, you gotta look like you made an effort, right.
Once you start shooting with them, theres no telling where youre gonna end up.

Good luck with your quest.
