I was a little nervous about buying this board because I hadn't heard of the company, but I'm so glad that I did. I've had it for a couple months now and I've ridden it about 200 miles. I'm so blown away by this board. It's as fast I would ever want it to be, it's powerful enough to pull my 200lb body up a hill, and the swappable batteries mean that I can ride it all over town. The nimbus wheels are safe and I can ride it on dirt trails. I liked this board so much I bought two of them, one for me and one for a friend for when they want to ride with me, and now I have 4 batteries that I can do with as I like. Build quality is sold, price is great, swappable battery design is outstanding. I couldn't be happier. I've looked for a better board and I can't find one. The nearest competitor is the exway wave, but it's sooooo much more expensive and it's a short board, I just don't think it measures up. I genuinely believe that the Uditer S3 is the overall best electric skateboard on the market when you consider price/power/range, and I'm so glad that I took a chance on it.
