LaserLyteLaser Trainer Switch Kit for Laser Trainer Cartridge with Replacement Switch, O-rings and Batteries to Extend Laser Bullet Use

My original batteries for my laser cartridge had died. This not only got me new batteries but also extra batteries and spare parts. The price was a very good value.

I had my fingers crossed when I ordered this replacement kit, but the "o" rings and batteries were a perfect fit!

Did not perform as well as my lasers in the past

Been using the Laserlyte for years in multiple calibers, great products! This replacement parts pack takes care of the only real wear point: the micro-switch that is struck by the firearm's firing pin - when it begins to wear out, the laser pulse becomes erratic. I deducted one star only because the listing on Amazon says "(12) 377 batteries" but only 6 batteries are actually provided. As the photo shows, the label indicates "(6) 377 batteries".

I was pleased that the batteries included were not alkaline like the ones in the original laserlyte. I checked the new switch and it screws on just like the original, and the extra o rings will be handy down the road.My original is still functioning just fine but the batteries had died and I figured this would give me future proofing.

Like this supplier and have bought directly from them and got exactly what I ordered. Now have to order them here and ordered three sets in Dec. First one was to have 12 batteries but only had 6. The price had been adjusted so that was ok. The second one came with 6 batteries but only got 4 and the brass fitting was missing. Returned for an exact replacement and it came with just 3 batteries. Don’t know who is shorting the boxes but not good. The batteries are not cheap.

This is the best version of this product and much less expensive than having to purchase a new one.

Needed to refresh older seal/washer and batts on a few calibers, and replace a worn out button. This worked fine and brought back accuracy
