Title says it all - I was going to pickup one of these for dry fire training and it seems they have a spring kit that can increase the tension to 10 lbs. I think it’ll be pretty suitable for the training group for the strength training piece.

That being said I knew a guy I did Jiu Jitsu with that broke two. Any first hand experiences with durability? Also, is it pretty straightforward to adjust the trigger tension? It’s kind of sparse on details on what’s in the spring kit. I’m assuming multiple springs that are color coated to indicate weight (it mentions a small card included).
Disclaimer: the guy that broke two - it wasn’t a huge surprise knowing the guy, but still I figure $100 is $100.
Thanks in advance!
