Ok once in a while but not often worth the frustration. Have been late for work because drivers who'd previously accepted had cancelled on me. The rating system is flawed and kinda messed up. There's nowhere that I've found that you can declare that you have trouble speaking - for example. Without that, drivers generally take it badly and think you're being off with them. Rating slides and it gets harder to be picked up. You vcan be perfectly polite + tips don't often help :( Wasted ££..
