Bests & Worsts Reviews from Amazon

I bought the original Anki drive for my son who's now been asking me for months for Anki Overdrive. This looked like it could be a less expensive alternative. What we ended up with was a cheap knock-off. The "tracks" are made of paper and, while they don't tear easily, you have to really be careful to not crease them as it won't come out. Additionally, there are so many batteries required I lost count. Overall, a disappointment. I'd be sending it back for a refund if it wasn't more trouble than it's worth.
