Poorly made

I'm repairing one of these and it's designed to fail. The main gearbox has a pathetic attempt at a shaft seal to stop liquids entering the gearbox which after some wear does nothing. The paddle gearbox itself has a main gear that has no bearings and instead relies on a nylon gear running in a nylon bush in the gearbox housing. Needless to say once this wears this causes the gear to chew out and strip rendering the gearbox useless. To repair it it requires the majority of the gearbox components changed. Once you factor in the labour and the fact the parts would be just as shoddy it is more cost effective to buy another machine.
