Query: not worth the money

this toy goes really slow.it only goes 14mph for 10 minutes.the rest of the time,it goes about 8mph.I put a custom speedometer,charged it for 2 days,and it would only go 14mph.in ten minutes it only went 7.3mph.A few days ago,i was riding it around my neighborhood and my throttle snapped off.to top it all off,yesterday my friends tire popped after hitting a rock.this thing is not worth the price.I recently got a gas pocket bike,which comes with a speedometer,and i went 34.7mph in 7 seconds!i dont have to wait 8hours to charge ,now i just give it some gas ,jump rocks,and go fast. P.S. the gas one was only 239 bucks!
