I bought this toy along with the Bowser set, Mario's car, Luigi's car, Yoshi's car and the expansion kit. The instructions were super easy to read and understand, and I had everything assembled in about an hour. The kids played with the set for four hours straight and would have kept going if it weren't for their dreaded bedtime. I have been obsessed with everything Mario Bro.'s since I was a kid and my son is following in my footsteps. I've always been kind of bummed that they didn't have some really cool Mario play sets and was out-of-my-shoes excited when I spotted this toy in Target. After coming to Amazon to post this review, I noticed that Amazon really has them overpriced. At both Target and Toys R Us, the little car sets are $12.99, the bike sets are $6.99, the Bowser kit was $24.99, and the expansion kit was only $19.99. Also, I believe right now Toys R Us has a special sale on all of these sets. If you can find them at Target or Toys R Us, buy them there...much cheaper.
I know this toy doesn't seem to be very educational, but if your child has trouble with their fine motor skills, any kind of lego set is a good way to get their little fingers working. Also, having to combine sets and come up with creative layouts that will include as many pieces as possible really gets their problem solving skills motoring along. And you can't deny the imagination that is required to bring this toy to life. I gave it the full five stars for durability because the cat has plowed through the track a few times, and as long as you have the pegs in to hold the track pieces together, it has yet to come apart. With a six and a four year old, toys don't last long in this house. I'm suprised that after 24 hours I haven't had to put the track pieces back together a zillion times. Five stars for fun, because...well, it's Mario Bro.'s!
Overall, I am very impressed that someone has finally come out with a durable and fun Mario Bro.'s play set. K'NEX really brought it with this product! I wouldn't be suprised that these start selling out once the word about them is spread. Hopefully I can complete the entire set before this happens.
