Was refered to this service by a fellow driving instructor who had been using it. I thought I'd give it a try as when my pupils fail I usually let them book their own cancellations. Thought it was worth a try booking them myself. Been very pleased with the service so far, works like a charm and managed to reserve dates and then hold them for hours after, super handy when I'm teaching and can't login in immediatly. Am defintely going to buy the full package. However, I give them 4 stars as there was intially a few bugs in their mobile web app, which I reported and they said they're currently working on. Will update if they get back to me
