Note for Update to last version:
 for all the exist customers that purchased the V2, when V5 goes out – i will charge a nominal/fixed fee of 50$ more.
Note for new customer about V5 future version:
when V5 goes out if you buy the V5 straight, there will be no offer/discount over a period of time,
it will return to the original price and even slightly more, so better to buy the V2 before.
