I'm an Apple fan myself. I have rented a number of times with them and we haven't had any bad experiences. Their prices are good, too. We are renting two scooters from them in December.
Keep in mind, all rental scooter companies will have issues, here and there. Scooters get old and break down. Scooters are mechanical. If you don't take precautions with using it in the rain and so forth, bad stuff can happen. You have to be diligent about watching your battery charge. Also, you need to be diligent about recharging your battery every night.
