Never used Lottery Harvester but I went to the web site and looked at Harvester 5 it sounds like it's just a wheel 16#'s 3if4in37c. You still will have to come up with the 4 winning numbers out of 16 numbers that you choose for play. They offer a numbers generator but I suspect it to be nothing more than a random number generator.
Save your money, get ahold of Covermaster or some other wheel generator or upgrade your LP membership and use some of the wheels that are offered here.
Remember you still have to choose winning numbers for any wheel to work.
Here is a wheel 16#'s 3if4in34c made with Covermaster. The numbers you see are just pointers, you just replace each corrisponding number with your own numbers (1=3, 2=10, 3=12) and so on.
