The quality of this little scooter is amazing Whoever invented this was definitely thinking outside the box.. 😂 It's got a little too much torque on takeoff and backup but you get used to it I absolutely love it This will be my second scooter and I have an everyday wheelchair but they are too heavy to lift up in the trunk of a car so I got this little scooter, I love the lightweight of this You have to be very careful on the turn radius as this machine because it does not slow down on turns and you will flip it. It free Wheels so you have to hit the brakes when you want to slow down or stop, you let off the throttle and it will keep going as it's in free will all the time until you hit the brakes..lol I had to learn that the hard way when I hit the wall trying to get on an elevator. This is my first experience using a key to remove a battery But I will get used to it. Be careful not to run it in water as the brake system is at the bottom of the front wheel.. it could cause a lot of issues if that gets wet, if it does somehow get wet by accident just quickly dry it when you return in door's. It's got it ups and downs but for me it works perfectly and I will get used to the odd things on this scooter that I'm not normally accustomed to. I give it a five star.***** And two thumbs up 👍 👍
