Thames & Kosmos Gecko Run: Marble Starter Kit: Includes Marble Run & Marbles, 1 count, Children Ages 8+

Super easy and my kids love it. As soon as they recieved it, they started setting it up and now its been up for 3 days and everyone that walks by has to give it a go. I'd say it was a good buy.

my grandson is going going to love this, what a cool way of doing marbles and you can buy separate parts to add on to the first one.

This is such a fun way to create a marble run (vertically). The only negative is that the adhesive does start to loose stickiness when it is continually moved around. Moving around is required since you have to adjust the run to see if it works. I wish there was an option for the magnetic adhesive so it can be attached to a large metallic surface.

This was a gift for grandson who loves assembling a marble maze. He did have fun but the stick doesn't work well on the painted wall. Maybe a bathtub wall or glass door will be better. Not a bad but mostly.

It arrived later than I had hoped as I wanted to be there when it arrived. I left Jan 4th and the texts kept saying "it's arrived" when it had only gotten to the state of Oregon. They sent me a picture of their creation on the door. I have saved the two extra kits for my grandson's birthday in March. I had hoped it would have either magnets (for refrigerator use) or suction cups so it could be used in the bathtub with water. So that was a disappointment too. Please pass this part of my message along to the designers or manufacturers. Think about these options. Sue Wilcox

very cool concept and a lot of fun when they actually stick to the wall. i washed my wall and dried before applying but we still had a lot trouble keeping them attached to the wall. we put the marble in all excited for it to work only for the weight of the marble to knock the tracks down. id suggest something a little stronger to hold the tracks up. it could be a fun time.

The tabs did not stick; if they did at all it was short term. My son was very disappointed because he needed something to work for his physics experiment and stay in place long enough for him to video the process or have the ability to bring to school. Great concept but if you can't get the components to stay in place it doesn't matter. The flexible tubing is a great touch, but it doesn't stay in place. Perhaps it should come with adhesive puddy or the option to purchase a "magnetic board" or some type of platform to help. If the items don't stay stuck on the wall (surface- hence name gecko), come apart after a minute, then you can use it. All the "kicks and giggles", add-ons, fun, or benefits to be had is lost if you can't use it. I am returning it.

This is just not it! My 4 year old has begggggged and begged me for a marble run! And I got him this for Christmas we were so excited to put up together he is that guy that likes it take off and do in different colors arts and you simply just can not do that! One good thing is it did not pee my paint off my walls but it just does not stick! Definitely does not stick if he takes off and tries to put back in a different way! Do not recommend this! Cool idea but just not fully functional!

Personally for the price I figured it would be more you know. It's just a few tracks and you had to buy all kinds of attachments to even make it “fun”

This does not stay on the wall. Now we have stickers everywhere and I'm hesitant to take them off because I'm scared our paint will peel. Don't recommend this
