I use it and the feature I like best is the ablility to download any updated lottery file anytime. Last night I was challenged to backup some statements I made about picking a bunch of pick3 combinations. I don't play pick3 so I don't keep records of the draws. I simply downloaded an updated file of Ohio pick3 file, posted my response to the challenge and plan to report the talley of that chellenge later today when all the pick3 drawings are over. Lottopro drawing files can be read using Notepad which makes it easy for me to edit a copy of them to be read by a GWBasic program I wrote years ago and continue to update which I prefer to use. That saves a lot of typing. The selections of wheels are nice but I sometimes prefer to use other perameters to chose my numbers. Everything in LottoPro is straight forward and it clear how the numbers are picked and wheeled and their files are always updated within 24 hrs. I once found some double posts in their Buckeye5 file, notified them and they responed and corrected the file within 24 hours. They don't make any gurantees, but they give you all the information you want when picking lottery numbers. With the free trial period, you know what you are buying when you decide to buy.
