Bought for my son's birthday. All excited, got out of box, before I'd had time to read set up instructions my daughter had switched it on and thrown it into the air, hence the vectron wave now hovers on the ceiling as it was never able to work out how much power it would need to gently hover!! Instructions clearly say to let vectron wave go through set up process - oh dear! Don't know if we can reset it. It is a wee bit dangerous too when played inside as it goes out of control when it hits a wall and flies at severe angles threatening to take innocent by standers heads off with it's fan blades. Good fun though!
