I'm very pleased with the ES1 with one exception. The cap bolts strip fairly easy when tightening or taking off. The head, not the threads. I wouldn't have minded paying a couple dollars more for better quality screws. But all in all it's a good scooter for the price. You won't find a dual motor scooter at this price anywhere. I really want the seat but will have to wait since this was a rather large purchase for me right now.
