Gecko Run takes classic marble runs to the next level with new creative challenges and less restrictive building requirements. This innovative marble run uses a specially designed system of flexible tracks that does not require any support structures. Traditional marble runs require lots of pieces to create vertical height, but with Gecko Run, your doors, windows, cupboards, bookcases – virtually any smooth surface – become part of your track, allowing you to build higher with fewer pieces. Attach the tracks to surfaces with the help of clever nano pads, which work like nanoscopic suction cups, to create a strong, but temporary bond. Because the pads are not glue-based, they can be quickly and easily repositioned many times without any damaging adhesives or sticky residue. A quick wipe with a microfiber cloth will keep your pads ready for action! The versatile tracks are made from renewable, durable, and sustainably sourced raw materials. Thanks to their wide range of motion and flexibility, you can create hills and jumps, and even turn corners to generate a limitless number of tricks and stunts. No two tracks are ever the same! Each unique configuration promotes hands-on experimentation, supports problem-solving through trial-and-error, develops motor skills, and encourages creativity for kids and their grownups! The Gecko Run Starter Set includes everything you need to zip, zag, bounce, skip, and hurdle into an awesome engineering adventure. A 16-page illustrated manual guides you through setting up your first runs and teaches you how all the different elements work. Witness physics in action! Use independently or combine with any of the expansion packs.

I want to preface this with I did NOT scrub surfaces with more than a soapy washcloth before starting this process, but some of the pieces just don’t stick well. Because of the scientific nature of this toy, there is a lot of trial and error with moving the track around. By the 3rd or 4th move, the funnel piece fell every time the marble went into it. It was a little too risky for me to put on the sliding glass door being it uses a metal marble….I can almost see the spider web cracking now….BUT I bet it would stick better on there than my refrigerator. Overall, my daughter still has a good time playing with this and rebuilding the tracks however play usually ends because of lack of sticking pieces.

edit: the 8 year olds I worked with ADORED this and the 5 year olds.... some were able to figure it out and found it really interesting!!! Others kind of struggled with how it worked and gave up and lost interest relatively quickly. And found another play choice in our space. I didn't have a ton of time to walk them through it and I didn't have that many track/etc/materials for each child but. But plenty loved this!The good: I have merely tried sticking 2 connectors, a track, and a catcher to my glass sliding door to my patio and it worked great! I was thrilled. It was kinda fun as a 31 year old assistant teacher and leader of an after school care program!The bad/surprising: I was absolutely NOT read for how FAST this marble run can potentially go if you curve the bendable tracks. It can go really, really fast. Maybe that's a benefit to some. Not really here. I work with ages 5 to 8, but MOSTLY at the 5ish age range... some kids can be really sensitive to stimulus and overwhelmed so the QUITE FAST and NOISY, as well, nature of this marble run was something I was not expecting and am not particularly pleased with. Also, something about the nature of this toy is pretty hard, honestly. Predicting where the potentially fast marble is going to go next and using your imagination and guessing to figure out where the next track goes is hard. Even for a grown adult. I'm going to try to put this out for some 5 year olds and the brighter and more mature of them but I have a feeling it won't go so good. I see a return of this product in my future.A shame I'll probably end up having to return it because as soon as I saw this thing I thought "Wow!" Because I'm always looking for toys with suction cups for glass doors. I was a pre-k teacher for ages. Kids love that type of toy beyond words and it also makes what was previously a ONE USE and almost useless part of a room (just a glassdoor for only exiting) in to a play space which is useful.Ugh. Hope this works out. Maybe I"ll update it. I could see a 12 year old losing his mind over this. But yeah. Probably not for young ones.Oh, and because it's so fast you could maybe lose marbles and even do so quickly, unfortunately. Ugh.

My 10 year old loves setting this up and rebuilding over different windows throughout the house and experimenting with different arrangements of the pieces. Super fun and educational!

Nano stickers. They will restick over and over... no they won't. This is a bunch of useless plastic pieces to not have any fun with..tried the wondow. Tried metal. Tried rhe wall..Tried every combination of press and hold and none of it stuck. This was a very expensive piece of crap.. all the pieces and directions were followed and present. This is the worsr marble run I have dealt with and I have all brands.of marble maze. Were marble crazy! Not for this one..I thought oh these are probably held by suction cups. Held by magnets. Held by something logical..nope stickers that don't stick.. so.many stickers that don't stick. I feel like it was a one time use marble maze but didn't even work the one time. Definitely expected at a place like dollar tree not a toy that was almost 30 dollars. Never ever ever will I buy this brand again.

My kids love the magnetic runs at the children’s museums, so I thought this would be fun. I guess I didn’t read and thought they were suction cups. They are sticky… which is fine… but I can’t see them lasting long, especially when you have to peel them off a few times to get the placement perfect. If there are other backing options, like suction cups or magnets, I think this would be a home run. My kid lost interest quickly because adjusting them because a burden. We used our back sliding glass door, but I can’t think of anywhere else we could use it.

7 year old loved it. Works well on a window. Haven’t tried it on other surface. More to think about than a standard marble run.

Bought this as a Christmas present for my son and as we’re sticking it to the surface the pieces are just falling back off. As far as assembly goes it’s a good product, easy to use. The stickers just aren’t sticky enough. Super disappointing too considering my son was wanting this so badly.

I bought for my 5 year old and it was too hard, but the older nephews enjoyed it. The marble falls out very easily but I acknowledge some of that is user error!!!But they did not stick well to our fridge, walls or even windows. I moved a big mirror down to stick them onto and they wouldn’t so I cleaned the stickers and then they stuck so well that it ripped them apart to even gently try to change the track. I liked them in theory but the sticky pads could use some work.

The idea was great and we really wanted to love it but they just don't stay up on areas they are supposed to, and areas they do stick they eventually fall off or just not sturdy enough to handle marble action - which kind of defeats the purpose.

I bought 3 of these for my grandson's they spend hours playing with it. The stickers aren't as sticky as I'd like so I used tape too. But apart from that even the adults love it. Excellent product for kids and adults too 😆

Got this for my son for his birthday, he loves to tinker and build things and this has so far given him hours of entertainment. it's great for kids who aren't into playing with toys, but are more engineer minded.
