This is the first scooter owned - I used a Lime scooter once only - so Ive nothing really to compare with- however I have used it a couple of times and no fault so far. I can go fast enough, spin the wheels on gravel and get up the road inclines in my areas - so I would say no issues with power. Not had a chance to test range - road time on one charge so cant comment. Build quality seems good - Im normally pretty quick to identify flimsy components, poor quality - but have not seen this...... yet but its early days. Manual is useless- you're going to need to spend time on line to answer questions you might have - but you're not going to make a scooter choice on whether the manual is any good! - you're probably going to get back to the dealer and the guys at Electric scooter shop are top drawer. Just one small niggle - pretty minor but the switches for eco/turbo and single/dual selections have lights which show when one or the other option is selected. The thing is that the switch light is on when the lower selection is selected for the upper switch, but on the lower switch the light is on when the upper selection is selected. Minor, just takes getting used to - and if that's the only issue, it makes for a pretty good scooter
