Supernova Blast Roller Coaster Play Set is rated 3.2 out of 5 by 23.
Rated 3 out of 5 by from One piece of track broken One piece of track is broken and I can't use that broken track. I bent it to much! Be careful on how you connect your tracks! Despite this, I still like the track and the booster and I still recommend this product. This set's track glows in the dark. The booster that came from my Supernova Blast Roller Coaster set still works well.

Rated 5 out of 5 by from Good Launcher for the Sonic Boom I've bought this product since November 20, 2015 and the launcher was good for a few runs on the actual build, and the Sonic Boom, it kept on going.

Rated 2 out of 5 by from poor speed I got this as part of a present and i built it correctly but still had not enough speed to get to the top, second drop, loop, or back to the launch. After awhile I took it down and built a nice coaster

Rated 2 out of 5 by from not satisfied i thought the instructions were very difficult and not clear in many ways also and I'm glad to see I'm not the only one to think so. Certain parts of the track we had to adjust differently than the book so the roller coaster car could fit through. Also of course one small piece broke and all pieces are important for the stability of the track. My son has adjusted the track and is playing with it which is the only reason I'm not returning it, but I'm not satisfied with how much it cost that its not together properly.

Rated 1 out of 5 by from Poor booster This was a christmas present for our nine year old, who loves building with K'nex. The directions were not great in some section - difficult to see where the parts go. Previous sets have had very good directions. However, the biggest disappointment was the booster. We tried 2 different sets of batteries (tested to verify they are at full strength) and the coaster car only went up about 1 1/2 feet, instead of the 3' to the top of the track. Previous designs are much better as they use a chain to get the car to the top of the track. Not sure if the booster is defective or not.

Rated 1 out of 5 by from Doesn't work. We could never get this to work.  What a disappointing Christmas gift.  The directions are to hard to see and the booster is to weak.  We have replaced batteries and put it together twice.  Still doesn't work.  :(

Rated 4 out of 5 by from Great Product I gave the K'NEX Supernova Blast Roller Coaster Building Set to my 9 year old grandson for Christmas. Although some of the instructions and pictures were not clear, we enjoyed assembling the structure together and he likes to play with it. Sometimes the power launcher does not send the car to the top of the structure, but most of the time it works.  I enjoy seeing the thrill in my grandson's eyes when he plays with it.
