Query: Speed Controller broken

When I got my e500 I was really excited. The speed controller of the throttle if you prefer was cracked. My dad taped it up but it still has a few problems. My friend has an e325s(a variation of the e300) and he has never had a problem with it. I can completely relate to other peoples reviews on Amazon. Razor customer service is poor. Scooter is fast and fun. I wish razor would do a better job sending the scooter.
