Rated 3.2 out of 5 by 22 reviewers.
Rated 2.0 out of 5.0 by 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 August 4, 2016
Rated 5.0 out of 5.0 by 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. July 1, 2016
Rated 1.0 out of 5.0 by Terrible my booster only went up 2 feet and i did everything correct. June 18, 2016
Rated 2.0 out of 5.0 by Poor Motor My motor isnt powerful enough to get to the top of the coaster. im thinking about giving it back to the shop. December 29, 2015
Rated 1.0 out of 5.0 by 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. December 28, 2013
Rated 2.0 out of 5.0 by 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. December 31, 2013
Rated 1.0 out of 5.0 by Terrible instructions First time buying product and will not ever buy another K'nex. The directions where difficult to follow and extremely hard to see and read. Parts also seems cheep and do not snap together very good. January 2, 2015
Rated 5.0 out of 5.0 by Great Gift My mom got this for me for Christmas and it works and I think it was worth the money December 30, 2014
