Seems pricey to me. The target is $100, and if you want to use their pistol it's another $50. Most laser cartridges on amazon from a search shows the pricing is between $30-$80 (and you want to use your actual pistol anyway right?) so lets say you'd need $150ish for this package. It would be $150ish toward something you can really only do at home.

For $20 - $40 more (depending on if OP needs an adapter plate), they can get a Mantis X3. I haven't used it myself, but at least for that price you can get a tool to use in both dry and live fire. I have heard good things about them, since you get more actionable feedback with all the charts and graphs and whatnot.

There was a suggestion of a dryfire mag, which I've also heard good things about...but it's also around $100. Working trigger control can be done without a live trigger, just takes some work: https://www.youtube.com/watch?v=beOVo1HQd30.

My dryfire routines eventually changed into just watching what the sights are doing when I pull the trigger or do any other drill. Only thing I had to adjust was to get brass snap caps (https://www.amazon.com/dp/B0116829BM) to simulate the weight of a loaded magazine when doing reloads.
