Orientation and experience: First of all, I'm a "returnee" to pistol shooting.  After a multi-year absence from having pistols, I bought a Glock 26 9mm three 3-1/2 years ago.  An old statement about pistol shooting: it's about 5 times more difficult than with a rifle. (Because the actual "support" for the handgun is the wrists which are the most flexible "joint" in the body.  May or may not be "five times" harder but it conveys the point - esp. in regard to the amount of practice needed.
Experience with the Lasermax for Glock 26 - only about 6 weeks.

Overall: it's definitely worth the money.  Amazon has a good price, nearly $50 below avg. retail.

"Effectiveness" - now here is something that deserves careful attention.  What is claimed may or may not be achievable (accurate POA at 60 yards).  Ask yourself: What do I need in the way of a self defense handgun?  According to my own experience and many published articles: the average distance for most domestic "gun fights" is about 7 feet!  This is partly based on statistics from police reports and accounts of  real life armed "encounters."  But there're myriad possible scenarios: you might need to make COM hits at 20 feet, but seldom at 60 feet (20 yards).  If you're carrying a concealable self defense handgun, 60 foot bullseyes is kinda unlikely for the average person.  So while the manufacturer claims 60 foot / 3" accuracy, it's a promotional claim which may or may not apply to every person and situation.  But it's not that important, either. Hitting an attacker at 7-25 feet covers "necessity" pretty well.
The advantage of the Lasermax is that you can actually see your aim point and that's an absolute advantage.

Some have seen Massad Ayoob's YouTube video on using laser sights. Those who have may have also noticed that he talks about this kind of sight as an aid in personal training.  He explains and demonstrates how a laser sight helps one train for "accurate" self defense shooting.  Even this highly trained expert didn't score all bullseyes at much less than 20 yards.  But he's right about laser sights being an aid to training.  So that's another advantage for Lasermax and all other laser sights.

Of course, one big advantage often mentioned for Lasermax is that it's all internal, no need to buy new holsters for your pistol.

Installation: all I can say is that "your results may vary" but self installation is doable for the average person.  Myself: I had a problem with seating the provided slide lock spring.  This MAY HAVE BEEN unique to my Glock but the spring just refused to fully seat.  I viewed the (very good) YouTube installation video (the identical video is available at the Lasermax website).  I also called Lasermax support - nothing seemed to answer why I couldn't get the slide lock spring to "seat" and thereby allow completion of the installation.  I came up with: using a small "blade" type screwdriver to press down on & seat the spring - rather than the provided 'tool" which is just a small diameter steel rod.  In addition: it looks like the slide lock from Lasermax is actually better than the ones Glock installs in it's own pistols. The Lasermax slide lever protrudes a tiny bit more on either side which makes is easer to pull the slide lock down to disassemble the gun.

Batteries: I can't really say but I see that some people report poor battery life while others report exceptionally long battery life.  I have 4 digital cameras - the same can be said for the batteries in those.  I've only had my Lasermax sight for 6 weeks, so far, the batteries held up  fine (even though I've "played" with the sight repeatedly during that time).  The real world: you can buy "new" batteries for anything and they will sometimes prove to be either good or bad.  Mostly good though. If you practice frequently: the batteries will run down faster.  That's the way it is.

Overall: the Lasermax is definitely worth buying and using.
