Laser Dry Firing/Target systems - I Target, Strikeman etc

[Riverboys]

Does anyone here use Strikeman or I Target or any similar laser dry firing system that you score using your smartphone?
I definitely want to purchase one since ammo is so expensive and scarce.
Any feedback or recommendations greatly appreciated.

I have this and it works well.
