I’ve got one. Been using it since August. More than happy with it. Good quality, quick to locate GPS, easy to use and seems very accurate.
I have never used any other GPS on a bike apart from on a mobile phone so have nothing to compare it to but would happily recommend it especially at the price on Sport Pursuit – I paid £100 from Evans.
They are not the latest models if that bothers you. The bluetooth connection to phones for calls and texts notifications doesn’t work with every phone so check compatibility if that is something you need – I don’t so it doesn’t bother me.
