One problem with these Reflex Sights as opposed to iron sights is that they use batteries, which are consumable, and therefore have limited lifespans. Since I bought the unit in May 2012, I have had two battery changes already. The first battery change came a month after I bought it. I think the reason why the battery life was so short, was because the battery that came with the unit was the generic, unmarked made-in-china type of battery.
The battery needed for the unit was the CR1632, and after the generic china battery, I bought a branded Panasonic battery for the unit for P50 each at one of the kiosks in the malls specializing in batteries. The Panasonic battery lasted about 5 months of fairly heavy use, until it gave out last week (October 2012).
