Two days ago I bought the ACE VR set up and started using the app. I can see after only using it for about an hour a few major flaws I have. I think the system isn't perfect in terms of accuracy and there is no recoil. But with all that said I would recommend if you want some simulation training you can do at home.

Anyone else using it?

Yes, It is a great addition to dryfiring helps with transitions and stage planning as well. I probably shoot 750 - 1k 9mm a week between two comps and training so being able to use the ace system really helps alot and lets me shoot more.
