★★★★★ Pay this much and you get the BEST!
"This is not my first laser training system, it is however my favorite. It works flawlessly every time and the accuracy of the laser "bullet" is spot-on. I tested it (and others) in a barrel clamped in a vice and compared it to my bore-sighter. The ELMS was the ONLY one to match my laser bore-sighter every time it was removed and reinserted. Other brands I own are off as much as 1.5" at 50 feet. This system was right on the money.
The app gives you the bare minimum and allows you to train only. Anything more and you must either download items from their website or PAY for app options.
Overall this is a great training aid. Worth the money too."
