  • (2023-05-29) J Berry: Best Of its Kind By Far!!!!!
  • (2022-09-18) Gino Mehl: I was really hoping this would work when I found it. Unfortunately, it does not. I can see contest details on the main page but as soon as I try to navigate or create a line there is absolutely nothing there. Sorry roto, I wanted to use you!
  • (2021-08-17) Josh Currie: Does not show any information on DraftKings like 95% of the time for me. The addon just does not work, I have to uninstall it and reinstall it for it to work again. Fix this.
  • (2020-03-18) Kevin Pillay: I am white.
  • (2019-10-09) Gallows: The Margin % this extension lists in the lobby is straight up wrong. For example, a $3 contest for 92,592 entries, $250,000 guaranteed price pool. 3*92592 = 277,776 277,776 / 250,000 = 1.111104 That's a margin of 11.11%, but this extension is showing it as 10.00%

  • (2021-07-27, v:3.40) Nick Errigo: ?/Prblm/Wondering/Thankful
    7/27 I always liked this....I use the chrome browser on windows 10, newer i5 Dell computer, plenty of RAM and Drive space but hasn't worked since I bought this computer.....over a year? It let's me log in and gives me options to check off what I'd like the extension to do, but the little percents on tourneys and the exposure under lineups,all gone. There is no sign of the extension even working but asking me to log in. I can't express how thankful I am you guys developed this extension. It WAS always useful to me. It was a great idea and saved me time from doing math in my head over and over. I really liked my exposure %...It let me know if I was getting to heavy with a player or person in the tourney i.e. driver, computer game player ect...Just thanks and it really stinks it's not running right on my software/hardware anymore! Take care- Leakedout

    Hello. I was just wondering if there is anything I can do to get the Pown percentages to display on the lineups page. It was working fine until all of a sudden they disappeared a couple of days ago. The other features such as the margin and overlay calculators are still being displayed. I appreciate the product!
