Awful. We purchased a blue & red 8" bluetooth swegway. After one day of use, it threw the rider off and one side of the board did not function at all. After trying to contact Iswegway's customer service, we eventually received a reply which asked us to follow a set of instructions (take photos of the broken product etc.). After following these instructions we weren't contacted anymore. We got back in touch with them eventually and they sent us the instructions (that we'd followed) again. After waiting hours on hold, we got through to a member of staff who told us to ship the broken product to them for repair. After waiting months, we received a phone call saying that they could not repair the product and that they'd send a replacement. When the replacement arrived, we were shocked to find that it was a plain 6" board, which, at the time, was £100 Cheaper! So in the end, they owe us £100 and, with the cost of shipping it to them, £150. WORSE PURCHASE EVER MADE. DO NOT BUY. The only product that met expectations was the carrier bag. For a reliable board, I would recommend purchasing a better product from www.ukswegways.com
