This was not easy to install on my gun and then the laser would go off after each shot.  Turning it off and on isn't easy either.  If I still had the box i would return the item.

Not only does it feel loose on my firearm, but after firing a few rounds the laser moved all over the place.
That's not very reliable, had to return.
No recommendation.

This slips over the handle and clips in. On my 9mm, after installation, it wiggles back and forth by close to a centimeter, throwing the laser a foot or more at 10ft. There is no way to tighten the sight. There is no set screw, just a roll pin that holds it on. Even with that in place, I was able to slip the sight on and off the pistol. Get something else.

I used it for the first time yesterday with my 9mm Jericho handgun. The laser works fine but the construction of this device is very poor.
After a few round, a small blade of metal came out of the front of the gun, it was the cover of the laser assembly!
Once at home, I removed the laser and slide back the metal cover but there is nothing in the front to really hold it in place so I expect it to come out again after a few round. This is not very well built and I suspect will not last long.

Received fast enough from Optics Planet. Installed on a PK380 and the laser would not adjust the windage to center. I called both Veridian and Optics Planet Customer service and they were both courteous and expedient with return labels.  One last look before packaging it up and sending it back ...... I am a tinkerer ..... so I removed both adjustment screws .. Used a pointed object to center the windage hole and installed the windage screw and then the elevation screw. I was then able to adjust the laser to POA.  The battery door does not want to stay closed, but put the supplied spacer dot on the door and when it is mounted to handgun the pressure will keep it closed. I haven't been able to try it yet on account of the Walther PL380 I purchased on 10/04/12 was issued a recall on .... You guessed it .. 10/04/12. Oh we'll ... Walther/S&W, Veridian and Optics Planet have excellent Customer Service , so it's a wash except for it's toy like design.

I sent the laser back for a refund. When I fired the gun the shock turned the laser off. I would never buy a laser with a rotating switch.

i would spend the money and get a good stanley laser level.  This thing has been nothing but problems.  It wouldn't turn or adjust and when I finally was able to get it to adjust, the laser kept getting week and dim.  I have a basic stanley laser level that I've had for 5 years that works better than this product.

Adjustments not working correctly.  I have verified that all mounts are tight but first 3 shots at 25 yards were 4" low and to the right.  I adjusted the elevation to move bullet impact up aprox 4"  The next three rounds were high about 2" and to the left 6"!  I then adjusted the windage for bullet impact to move it to the right.  The next 3 rounds were to the left and low. This goes on and on.  I kept doing this for about 30 rounds and have given up!  I have been shooting for 40 years and have never had a scope act like this.  I also don't like having to focus the scope for each range.  The focus is hard to turn and a hassle when you change target ranges.

Bought this to use in a 308 and its terrible for it. The laser is stamped "cal .243 win" but package says also for. 308 and 7.62.  It moves too much in the chamber makimg it nearly impposible to get it right as everytime i chambered the laser it would move off my crosshairs.  It might be perfect for 243 but not for my gun wasted alot of rounds chasing it to sight my gun in.  Do not recommend for .308 would have gave a 3 if the laser light didn't dim after a few minutes of use

As the other reviewers have stated there is no on / off once the batteries are in.  Even with the end cap off the laser activates sporadically.  That being said, a switch such as one like the end cap on many of the newer flashlights (ie: SureFire 6P) might be a good enhancement.  But removing and installing the batteries would probably offset the cost, anyway.

As for the accuracy, it seems the laser is not 100% accurately mounted in the cartridge.  The only way to be certain is to take it our, set up a bench and a stand and take it from there.  That will be my next step.

the gun came with a laser which was fairly faulty and off by about two inches on either side. The gun itself is a cheap plastic which jams at least once a reload cycle and only allows for approximately one hundred feet of distance. the product was priced around nine dollars, and there are comparable guns on the market which have better reviews and similar features.

My first impression of this laser was that it was built very well and appeared durable. Less then two days after putting it on my pistol and carrying it around a few places, I noticed that the cover for the batteries was loose. Upon further inspection I noticed that this little PLASTIC cover was no where near the quality of the rest of the laser. Its crap. Plain and simple. The cover does not snap, it does not pop, it just "sits" over the two batteries and it is very insecure. This is a big problem for me as I carry this pistol for personal defense and use it daily. I particularly use it in my home and would like to rely on the laser in low light situations. If the batteries fall out for some reason then I am stuck with iron sights or just pointing and shooting... in the dark. Don't get me wrong, I am capable of shooting irons sights in low light, but the whole reason I bought this was to assist me in low light and without the batteries this thing is completely useless. Fix the issue and I'll gladly give it 5 stars. Otherwise and until then I will secure it with tape and charge on. Come on Walther, you can do better than this!!!

Really wish you could move the laser left/right as well as forward/backward.  It would make the use of the product a little better

The laser turned on to work in manual mode but would not switch to the automatic mode to move on it's own.  That is the whole reason I bought it.  If I wanted to have to move the laser myself I would just use a small handheld laser.

The laser doesn't hold it's shape once inside the rifle. I tried it with multiple ar's and with each one, the laser is blurred and misshapen.

Right out of the box there were issues. Laser is nice and bright with multiple choice of which laser dot you might want to use.
Laser projects two dots on target, each was of same intensity. After about two minutes the two  dots became one and started moving
slowly downward....Sent it  back for a replacement. I hope the next one works.
I will say Amazon customer service was top shelf.
