BTA Appointment Booking App

Works great.
We had some problems in the beginning, but they are very quick with responding and resolving problems. You have to consider a lot of ittt's for rental and they manage to control them all.
If you ask a question if something will be possible, they not only answer, but manage to fix things before the answer.
Of course depending on the day and hour, but often they answer within an hour!
Could not wish for more at this point.

UPDATE: 5 years later: It's still working like a charm. Had some problems with integrating into a new theme, but they helped me out on the same day without any problems!. Keep on rockin'!
