K'NEX Thrill Rides - Web Weaver Roller Coaster Building Set - 439 Pieces - Ages 9 and Up - Construction Educational Toy

I chose the K'NEX Thrill Rides - Web Weaver Roller Coaster Building Set - 439 Pieces - Ages 9 and Up - Construction Educational Toy as my son, since he was little, has told us he wants to be an engineer. Honestly, he's nine now and I admit it's been hard to pull him away from the video games, so I wasn't sure what to expect. He's already abandoned his Legos. I have to say; my son was thrilled when the box arrived. He immediately got to work putting this together. I wasn't sure if he'd be able to do it alone, but I was still working at the time, so I had to leave him to his ministrations until I was finished working. Surprisingly, he finished before I did! It didn't take him long at all (approximately one and a half hour +/-) and he never needed any help. Obviously, this set does have small pieces, so depending on your child, he or she may need adult supervision and/or assistance. He said he rated it a “10/10” when I asked him, and noticed he played with it after completed a few times, but I admit, he's already abandoned it. So, I think these sets are great, I just don't know if they can hold their attention long.

My son loves K'NEX and this is a rather large set. Good quality that is typical of the brand. The instructions can be downloaded and your child can either copy the design or make his or her own. My husband did have to help with some of the assembly but that would be typical of such a large set. Once it's put together the motor works to bring the cars onto the tracks and they then go down the tracks like a roller coaster does. It does require two AA batteries, which are not included so you'll want to make sure you order some or have some on hand when this arrives. Very interesting set. Great for engineering/design interest development and shows children how gravity/momentum work. This is definitely one of the more interesting sets we have.

My kids love the K'nex sets. They are a little challenging to put together but worth it. My kids love a good challenge!! I'm going to say this it's very time consuming We chose to do it as a weekend project and it worked out that's great for the whole family. After we got it started the kids were very excited at our the pieces was easy to use my boys are BIG roller coaster fans and We love how these Construction/Engineering Educational Sets challenge the kids even the BIG Kids (dad) it's a wonderful way to help the kids read build and solve problems. I really enjoy watching my kids playing with the K'nex and actually doing something more hands on other then holding a controller for hours kids need more K'nex products in their life and need more interactive things kids today are so consumed with electronics they are missing out on the simple fun things in life!! Thanks k'nex For allowing kids to have a challenge and building memories at the same time my boys needed this challenge!!

When I was a kid and went to any theme or ride park I would look up at the roller coaster and say who built this thing. Now your child can build their own idea and have it run. It amazing how they developed science and construction in a toy. You have to use your mind to construct your own ride using the 439 pieces they provide in this set. Talk about having fun but, seeing their face as they have completed it is so wonderful. You will keep hearing about it everyday. You have fun while learning it's a great gift.

As my review title says, this is a special type of “toy” and I say that because this is nit anything like the building sets your child is used to. This stuff takes concentration and commitment. My 12 year was having a good time playing with thenkartsbuntil we decided to actually make the item in the directions and that's when it went left....he got frustrated, annoyed, and lost interest after reading g through these directions. Now I could show pics of the random parts put together but you can see that anywhere so I'm going to show you the instruction book. This is not something for the easily distracted. In fact, even my husband walked away from it about half way through lol. In my opinion, it's a great brain tool. If you can get your kids to focus, they'll be busy for hours!

This roller coaster set is so cool even I wanted to play with it. It is a buildable roller coaster that you can put into action once you finish it. My kids were very satisfied with this toy and loved putting it together. This helps children learn construction skills. It works their minds which every parent wants. This is definitely a great gift for any child

This was the first time our son was interested in building something with us and he loves it. I must admit, it was a little confusing at first, but I tend to focus on the easier-looking creations first and it got easier. When putting the green claws on the tracks, be careful with how much force you exert because my husband broke a rung of a track quite easily. Also, when you get the car moving, the tracks don't stay on the claws no matter which way you lay the tower but the car stays on the track and that's the most important thing. Also, the car got stuck when we laid the tower horizontally but never got stuck in its vertical orientation. We love that you can create any track style that you want so it makes for plenty of fun times and kids won't get bored with it quickly. And the coolest part? It looks awesome in the dark and the batteries are rechargeable! Now, the only con is that the car is loud (sounds like an electric drill) but I'll take the sound of fun over nothing at all.

This is a good build set with creative think and some degree of coordination. It would be a great project for a Sunday afternoon. The set came with detailed step-by-step instructions with illustrations. There were no missing pieces. It took an adult about 5 hours to complete. The electric car presumably took equal amount of time or less to charge (it was plugged in at the start and worked fine after the roll coaster was completed). I was pretty amazed at how sophisticated the roller coaster was designed how smooth the car can speed up and down the set. That's said, I believe there are a few things that one should be cautious about. First, the car travels extremely fast through the track and does not have illumination by itself. However the tracks are fluorescent. Therefore, if you plan to test this set in a dark room, please ensure to put safety googles on. As when in the dark, the whereabouts of the car could not be easily identified. At the speeds it travels, one could easily be hurt if the car flies off the track (not that it happened to me, but just to be pre-cautionary). Secondly, also because of the speed of the car, it actually mobilizes the entire roller coaster, making it shake and wobble, and relocate itself quite a bit. It gets a bit better when on the carpet. This is not a potential safety concern though.

Building the k'nex pieces wasn't so bad. You just have to be careful to make sure all the pieces are facing the correct direction. We had to pull a few apart. When it came time to build the roller coaster it got difficult...some of the tabs didn't snap correctly, some of the pieces were difficult to maneuver and my 10 year old ended up needing adult assistance. We finally got it out together but the car didn't work as expected. The fan was powerful and when the car made it around the track once it was really fast. After that it never made it a full loop around. It'd go for a second and then just shut off. We tried to see if it might be user error but it was pretty basic so we didn't see what we could be doing wrong. We did like that it charged by usb rather than battery. Just think it needs a better design.

We have had other K'NEX sets, but this was the first thrill set we ever attempted to put together. It looked awesome on the box. It came with 439 pieces and no extras. That's right. Don't lose or break any because there are no extras! My 13 year old worked on this for 4 hours before realising the parts she needed next were broken. Now there is a half constructed monolith and it's parts littered across her bedroom floor. It is very disappointing. Also the directions were not very good.
