I have been thinking of getting wifi for sometime but this past summer I got a chance to see it in person at Gerry Morlitz home. It was amazing the short time I got to use it.
This past York I decided to buy it and install it. After some issues hooking it up that were totally my fault I put my first engine on the track and added it to my iPad and ran it, I am awestruck on how well it worked and this was on the free app. I then upgraded to the premium app and it is even better.
If your hesitating using wifi because you think you are too old ( I'm 72 ) or not techie enough ( I'm not ) give it a try, it is great IMO.
Now back to the fun.
