It looks as if people have been having great difficulties with ordering and receiving but I can only say that there was no problem (we didn't try to order it on December 1st for a 2-day delivery).
As far as the product, it was purchased for my 10 year old son. He got the 10" wheels and it only took him a few moments to be quite comfortable on it and after 2 days he is VERY competent. He loves it. Rode it to his friend's house (1/2 mile away) and back a number of times with no problems.
He does not take it up to a high speed, and he must wear a helmet but I find it to be a very impressive product so far.
