hi
i have had it about 4 months now and if you can take film clips of your swing then this will help. if you cant take clips then you miss out on 70% of this software.
not only only show you what's wrong with your swing but gives to drills to help the you fix the faults some have 5/6 drills to help with one fault, you really have a lot of choice with this setup, nothing else like it and yes it uses v1 upgraded software. i dont like leadbetter much but he is a great swing teacher.
best interactive software out there.
