A frustrating experience!:
This was received as a birthday present, and I'm sad to say that I would not recommend this product to anyone! My 10 year old son and I have been working on it all day, and it's still not assembled. He is getting very frustrated, and as for me, I'd like to throw the whole thing into the trash! The main problems are: 1) There are NO extra pieces. So if one of the many little pieces is misplaced, too bad, there is nothing to be done except leave it out and hope it's not important. If they had only put in some extra pieces, much frustration could have been avoided. 2) The diagram is very difficult to figure out. We needed a magnifying glass and a flashlight and it was still difficult to figure out how to properly connect certain pieces. The colors are rather indistinct on the diagram which does not help matters. 3) For some unknown reason, certain of the stabilizing bars do not connect correctly and thus cause the other pieces to twist. We had to leave out some of these stabilizing bars and are hoping it does not cause the coaster to be weak in certain places. 4) We have just begun putting on the track pieces, which has presented a whole new level of confusion. For the life of me I cannot figure out from the diagram where the track pieces go. My son is doing his best, but it is nearly impossible to tell how the track pieces relate to the frame. We are using the picture on the box more than the diagram. When we finally get it finished, I'm sure my son will enjoy it, but I think K'NEX needs to go back to the drawing board on this one!
