DollaTek 5Pcs Smart Car Robot Plastic Tire Wheel with DC 3-6V Gear Motor for Arduino

Motors are very good, sort of robust and spin well.They are let down by the little tabs that you solder the power wires to. They are really flimsy and have snapped off when knocked gently.I have realised why products such as these are supplied with battery wires that re marginally thicker than a human hair... it is because they are easier to solder.

Don't rely on them all working, some of them might come with broken gears/misaligned wheels.

L' articolo è buono l' unica cosa è che non si è pensato bene al fissaggio perché mettendo le viti toccano la ruota , i fori dovrebbero essere nell' altro senso in modo da non interferire con la ruota .

Très bien
