Also , yes I added a lot of things to ours also, better headstraps, and eye pads sort of , as I need my glasses most times. Extra battery pack and chargers that just click on the back of the new head strap, so we can play for hours with out stopping, because the time goes fast.
I have not been on mine for about 6 months as I have been very busy. But Mona uses hers every other day.
There are lost of interesting game/programs.
I also like the one where you can put in the name of a place and actually seem like you are walking down the street of said place, I have been to the beaches of Rio, Dublin Ireland and Batton Rouge, to name a few.
