The app glitches allot and changes dates to the current date constantly which makes navigation a pain. Make sure you verify everything before entering you credit card info because there will be no refunds from this company.
There customer service was good for me unlike most reviews here but they were unable to simply change my tee time to a different date. As stated above the app changes dates frequently even after seeing the date you are looking for. If you use their services be prepared to call your credit card company to dispute the charges.
Will never use the service again. Some flexibility on their part would probably improve the reviews they have.
