User reviews

Rubbish, never works when you need it

Bring back voi, tier scooter app is terrible and crashes all the time, pointless and can’t be relied on for people to get home safely. Dangerous to rely on and irresponsible to put in place in Bristol over other methods of transport

Terrible app

Cannot even signup, “we’re having issues, please try again in a moment”. Tried multiple times on 2 different devices (Apple & Andro); same result. Junk

Faulty scooter steering broke my iPhone

They stalled and said their insurance would help but never did..tried to co tact Tier. Tier said Marsh & Parsons would reach out. Marsh & Parsons lied and said someone had reached out to me and couldn’t get hold of me ..
On top of that - after reporting it faulty they did not take it offline but it stayed in service when the steering was loose ..and my 1 month old iPhone was attached to the steering for navigation and got shattered
