REVIEW OF THE SECOND ONE I RECEIVED: FOUR STARS:I stand by my original review listed below. However I have received my replacement and after a few sessions at the range it is running strong and I really like the low profile. Again, installation and sighting it in was child's play. A couple small tweeks with provided allen wrench and it was on the mark. I never bothered to look at the instructions on either one because its so simple to install the battery and install the unit on a pistol; one look and I just knew what to do. I like it and it does what it is supposed to do, so far, so dont get hung up on all the negatives I list. I gave it four stars. This may change in the future depending on longevity. Only time will tell.Use some semi permanent loktite on the threads. I used Small Thread Loctite 222. This will eliminate the screws coming loose like some others have mentioned. Red laser is nearly impossible to see in broad daylight. No different from others. If you want an outdoor daylight laser buy a green veridian. Double the price though for green. Indoors or dim lighting... works like a charm and the laser has cool factor. If your dot starts to look like a huge snowflake it is because its dirty. Q-tip and alcohol spun around on the lens should clear it up. I am leery about using gun solvents and oils on it myself.Same issue with the laser being hotdog shaped and much larger than advertised. See picture below. Same issue with the lip of the rail insert being too short to properly engage the rail. This insert seemed to engage just a little bit more then the first one and I believe enough that it would NOT be able to slide past the notch. However, the lip on the insert is smaller than the groove in a picatinny rail and thus could potentially allow approximately 1/8" of movement front to back.I am not sure how I feel about the 5 minute shut off timer. I understand battery saving if it is left on or accidently turned on shoving it in a range bag or holster. However, something like that could get you killed if you need to reach for it at the wrong moment. *SHRUG* That being said the "wings" buttons on each side are nice as I can reach them with my trigger finger.BELOW IS MY ORIGINAL REVIEW FOR THE FIRST ONE I RECEIVED: Review was TWO STARSFew things to note: Not a .50" dot at 50'. Set it on my table pointing down the hallway and measured the "dot" with a caliper. More like a hotdog shape .75" at 30'. Also, the two pieces that squeeze together to mount when you tighten the screws do not sit in a fixed position in relation to the laser. If you are not paying attention, and mount with them too far back in relation to the laser, the little finger piece that engages the rail slot will not be captivated and you will lose it. Luckily I noticed and remounted moving them more forward with it captivated. Also on that note, the little tab piece that is supposed to go up into the slot, barely went up into the rail slot at all and so little in fact that I figured it may be able to simply slide right past on recoil. *SHRUG*On a good note: it was easy to install. Childs play in fact. Adjustment/zero'ing was childs play as well. couple small adjustments to each direction and the dot was right where my sights told me it should be. Unfortunately I never got to use it at the range because after using several mags with the iron sights it would not come on at all. Pushed both buttons several times and made sure the lens was not simply dirty. No go. so I returned it. I wont give it a one because it could have been a fluke.Looses one star for dot basically double the spec size. Another for the real possibility of loosing the little rail engagement piece. and yet another for that piece not fully engaging up into the rail slot.
