K'NEX Architecture: London Eye Ferris Wheel - Build IT Big - Collectible Building Set for Adults & Kids 9+ with Motorized Movement - New - 1,861 Pieces - 2 Feet Tall - (Amazon Exclusive)

My nephew love this knex set. He was so excited to build it ...

If you are looking for something to do during the current lockdown; something that will exercise your brain, the K’nex Architecture Series may be just the thing for you. The London Eye was my second purchase and build from this series of three. The first step was to separate and count the various pieces of which I had better luck than other reviewers as I was not missing any pieces and was giving extra pieces on some parts. After separating the build was on. No problems with this build as the step by step instructions were very clear. The only downside with the build has been the actual rotating of the wheel in that it rotates for a very brief second then stops. I have yet to determine if it is that the motor is weak or that it is hanging up for some other unknown reason.

This is not for young children. It is intricate and complicated. Challenge which my hubby took and won!. My hubby is a PhD physicist with an engineering background. Turned out Great! Intricate but precise directions. Fun to turn it on with the battery motor.

It's very nice product comparing to Lego this one is worth of the money and the design looks very nice as well

Our very gifted 10 year old grandson is having a very hard time putting this together

A building kit.

It is BIG. I finally got the Eye together and learned that it would not rotate easily. More about that later. The box was packed in an outer box and well protected. The instructions, at best are poor. Because of the complexity of the build, much better representation of the three dimensional structure is needed. Some of the pieces are very difficult to "snap" together, either my fingers were too big or the strength of my fingers was too weak to get a good clean snap. But with some perseverance and a lot of patience, the job got done. The kit was missing two pieces. On the two occasions (one for each of the missing piece), I found their Customer Service representative helpful and efficient. I received the critical part quickly and just requested the other missing piece today. So, in my book, the Customer Service group gets five stars. It's not an easy kit, but it can be done. The problem, is the instructions and the lack of good 3D images of what is being built and how it fits into its final position. The instructions get one maybe two stars. The enormous wheel fits onto a cradle and is supported around its outer circumference by four wheels, one of which is a friction drive wheel connected to the motor. There are four additional wheel supports which help keep the wheel perpendicular (aligned) in the cradle. The problem is the structure is not stiff enough to support the wheel or keep it aligned. In addition, the wheel itself is made of straight pieces, forced to bend into two large radii (inner and outer) bands which form the wheel. It did offer some resistance when the wheel was formed. But I was able to form the wheel and was quite surprised that the wheel was in fact, round. The wheel is made of rods and connectors (which are slightly larger then the rods). The wheel starts rotating with the motor but is then caught by the connector and stops. Friction alone is not enough to keep the wheel turning smoothly. I have seen several YouTube videos of this build and do not understand what I did or didn't do to cause this problem. As far as I can tell, my wheel is constructed properly, it just does not turn smoothly. I intend to keep working on it but have little hope that it will be an impressive thing to look at but not to rotate.

This is an impressive model but the pieces are smaller and thinner than usual, making it quite tricky to build. When dismantling one piece actually snapped. It also didn’t run as smoothly as I would have hoped.

Bought this as a Christmas present for my daughter, opened on Xmas day, assembled Xmas day night, after spending hours and hours assembling this with her and watching her getting increasingly excited to reap the benefits of her hard work we got to the last few pages only to discover there were parts missing!!! She was heartbroken, luckily a neighbours child also had k-Nex and gave her the missing parts!! Amazon! Sort out the contact seller option here and make it easier to do so! We were both very unhappy with this purchase
