Ade Advanced OpticsHG54G Green Laser Sight – Rechargeable Universal Rail Mount Pistol Accessory with USB Charging, Constant/Strobe Modes, Ambidextrous Switch – Compact Class IIIA Optic for Handguns

1. The laser will run continuously for about 7 hours straight before turning off. I could not believe this so I ran the test three times. Same result. The green laser version only lasts about 4 to 5 hours in the test.2. After it turns off, you can turn it on again and it will run for 5 minutes more. Several times.3. This means you can turn the laser on before you leave the house. Holster it and go out for 6 or 7 hours and not have to worry about turning the laser on if you have to use your pistol! So the switch is not that important any more in most situations. Also it's rechargeable, so replacing or running out of batteries is not a concern!4. if you turn it on in the blinking mode, it may last even longer than 7 hours - i haven't tested this yet. The blinking function is often used on laser sights to extend the battery life, so re-read point number 3.5. It did not show any adverse symptoms under heavy recoil. Just be sure you tighten it down good. Mine loosen up after a few shots, but is no very secure after I re-tightened it harder.6. The red beam is as bright, and big, as any Crimson Trace laser I own, (3 of them). The green laser version is also very bright, as green lasers tend to be. Pick your favorite color. Both are very bright in the low light/dark. Both are almost invisible outdoors in the bright sunlight. All laser suck in the bright sunlight outdoors. You will never be able to see a red laser against a reddish background in the daylight or a green laser against a greenish background. You have to be very close 3-5 yards from a reflective (white / light color) background to barely see the lasers in daylight. If your target is in a dark shadow, you might do better. Just plan on using your regular sights in the daylight outdoors.7. The switch is a bit harder to turn on then some, but also less likely to turn off accidentally. I like the switch and it works distinctly well. Re-read point number 3. Turn it on and leave on in your holster while you are carrying.8. The battery is replaceable if you wear it out; that's good. The magnetic charging head is a great idea. No need to worry about breaking a connector is you grab you pistol in an emergency while it is charging. It simply will fall away without hindrance. Use a 10,000 mah battery pack to charge it up while in your safe, etc. There is a red LED light to tell you it is connected and charging. That's good too.9. Adjusting the sights can be sensitive. A small turn of the Allen wrench can swing the laser quite a bit, so be patient and adjust slowly in small increments. Pretty much the same for all the lasers I have owned (9).10. Overall I am well pleased with this product.

Very nice, super compact laser. Both solid and flashing modes are a nice addition. Perfect fit on G26. Finger position for ambidextrous switch is perfect and easily adjusted by sliding forward or back on the rail. Easily zeroed. Just returned a $300 guide rod laser because it was not accurate, had only flashing option and had no adjustment options. Not to mention it was a red laser. This was less than one third the price and has all of those features as well as a green laser which is much more visible. Rechargeable as well which is another plus over the guide rod laser with $20 battery packs that need replacing often. Laser can stay on while charging with USB cord with the convenient magnetic charging connector.Great laser with all the features and convenience at a fraction of the cost of others with less adaptability.

I've been interested in getting a laser and trying it out on one of my pistols. Have been looking at the Streamlight TLR-2 HLG, but with a price tag over $300, I wanted to try something a little cheaper first to see if I even liked using a laser. In steps the Ade Advanced Optics HG54G. Mounted super easily onto my Glock 17 (Gen 4). Activation button sits just under your extended trigger finger - no problem turning on and off. The green laser is super bright and shining on a wall 15 yards away is not washed out at all - looks great! A quick adjustment down and to the right with the supplied allen wrench and now the beam sits just on top of my front sight post when my iron sights are aligned. Plugged the supplied cord into a USB port and the magnetic end jumped right onto the charging post on the laser. I love that it's rechargeable and doesn't require me to keep feeding it batteries. I have a similar rechargeable Olight and it has been great. Will test the laser out at the range this weekend, but I am very pleased with this purchase.

I like the design I was able to print a Pic rail for my 365 xl. Went on easy enough. It's raining so I cant go to the range and test it. It seems to be solid. The push buttons are a little firm for my liking but maybe they will ease over use. The magnetic charger is a great idea but I don't think mine works correctly. The charger won't seem to stay connected. I have it propped to charge at the moment.

Bought this item going by the reviews. The item I received must be a newer or somehow different version because the rechargeable battery is indeed removable through a rear screw plug and it is a radial Lithium capacitor type battery I have never seen before. The housing is aluminum and appears the same as pictured except for the side slashes (///) which are more like three (XXX's). Seems quite sturdy and the green laser is plenty bright. The dot is clearly visible in bright daylight in either constant or strobe mode. Visible farther than I would normally consider targeting a pistol. So yes...I like it. I checked ADE's website but there really is not much info on this item. What I received is better than I expected. It is odd the listing doesn't even mention the housing is metal. I half expected it was going to be polymer like most of the other lasers out there. Good quality and the price is right.I mounted this on a Sig-P226, it looks good and fits perfect.Ran this laser for a total of 3 hours straight on a full charge before it finally shut off. The laser dot was bright throughout the entire test run with no apparent change in output. Again, I did not expect even the listed 90 minute operation but three hours! Either I received a fluke or this is just plain amazing. Re-charge time was about 1.5 hours.
