The TRX Personal Transporter Scooter came with a bad battery. NO PROBLEM. I called the 1800 # on scooter. They are shipping a new pack of batteries. I went out and bought batteries myself also. This thing flies. Great for a door to door salesman like me with a bad back. I will be doubling or tripleing the number of doors i knock on in the evenings. An engineer friend of mine is building a quick change fitting so we can deplete one battery pack and then use the second that is being sent to me. This tool will earn me a fortune. Payoff in under one week. I will be buying a second for our second door to door salesman who accompanies me. Some tips to those buying this scooter. A cordless drill with a phillips bit and a socket set make replacing the battery a breeze. Call tech support (Emily was a big help) they stepped me thru the process. (Charge the scooter, remove cover, test output power of battery pack. Should read 36 volts, mine was 24 volts.) The scooter even comes with a small tool kit. All parts are available thru the 1800# . They even sold me a second battery case and two electric charger input plugs for my quick change battery conversion. Save the box and packaging (for returns). Lean forward when pulling the throttle. In the winter months my wife and i will be taking the scooter to warm weather tourist spots. Should be fun. MY SECOND CHOICE TO THIS **** SCOOTER WAS A 6000$ SEGWAY. Incredible. The scooter unlike a segway has 4 wheels to prevent tumbles. Skip the segway, buy the scooter and spend the ***** on great Italian meals. Happy Scooting.
