Failure x2 - Vortex SPARC Solar 1x31 mm 2 MOA Red Dot Sight

My first sparc solar lasted 6 months then the battery died. I figured out that the auto shut off was not working and possibly the solar recharge. I returned it easily with their vip warranty and received a new solar with the report that they found the same problem that I did and apologized with a new solar. The same thing happened with my second solar except within 2 weeks. I will return it again but will go with holosun or trijicon.
