Bought Swegway 6/09/2016 sent it back as it judders and threw my son off injuring him. It cost me £20 to send it back and a further £20 for a repair even tho I legally should have 12 month guarantee.. the fault still persisted...I had another Swegway purchased on eBay the gyro went on it so I replaced it myself...in the box with the new part was a check list ...LISTEN UP UKSWEGWAYS JUDDERING IS NOT OPERATOR ERROR IT IS CAUSED BY THE FOOT PLUNGERS EITHER WEARING OR NOT TRIMMED CORRECTLY...you can imagine I'm very angry as he only had it 1 week and it threw him off not enough time for wear and tear... By the way I'm an electronics engineer and will not be buying from you again the batteries in your Swegways are not badged up at all as either samsung nor lg Since you didn't go not your statutory obligation of 12 months guarantee I didn't see the point in not looking inside myself ...be wary your statutory rights are affected with this shocking company..
