The Trigger Trainer: Learning Smooth Trigger Motion & Avoiding Shoulder Fatigue

I ordered the Trigger Trainer with the intention of using it as a training aid for beginner shooters. I think it will prove to be useful for learning a smooth controlled motion straight toward the rear as a foundation for trigger control prior to applying it to the actual handgun. Many new shooters start with a very jerky trigger motion when a gun is put in their hands too early. My theory is that allowing the hand to memorize a smooth motion with control on both the press and release will help to avoid a jerky motion later down the road. The Trigger Trainer claims to promise an increase in marksmanship with minutes a day. I'm not sure about that because I don't intend to use it that way. I wouldn't want to replace my dry fire practice with the Trigger Trainer, though it may prove to be a good conditioning/strengthening device for the trigger finger and muscles in the forearm, which I have trouble with due to Tennis Elbow & Cubital Tunnel Syndrome. This is a brand new device, so there's not a lot of research or experience out there. I look forward to seeing results with new students and may be doing a follow-up video later on. I do know from personal experience that the repetition exercises with 1 lb dumbells do work to condition and strengthen the shoulder muscles. This would certainly work with the Trigger Trainer, given it weighs 1.25 lbs. Plus, you'd have the added bonus of a trigger press with each repetition. I'm initially disappointed that there is no reset...but I do understand their reasoning behind leaving it out. They suggest that a click causes some anticipation as the shooter waits for it, causing slight inconsistencies in the press. The goal is a smooth, continuous press and a controlled release.
