Gecko Run Marble Run Starter Set by Thames & Kosmos, Toy of The Year Winner - 63 Piece Vertical Marble Run, Flexible Tracks | Fast, No-Mess Setup, Residue-Free Nano-Adhesive Pads, Creative Play

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 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.

My grandson loved this game. It was perfect for a four-year-old who loves marbles. Easy to put together and you can make different designs with it.

I bought this last year and still haven't even used it. I'm making a review a year later just because I don't want others to waste their money if they're not patient like me and don't want to spend a whole entire hour setting it up. This is not a easy assembly whatsoever so in my opinion it's frustrating. It is not fun. The functionality sucks. Not to mention the magnet strengths is not strong it barely sticks unless I got it defective one. I just simply don't recommend especially for children under five.

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.

Bought for grandchildren they love playing with them and critical thinking

Didn’t stick well but was still fun. Wouldn’t buy again though.

My kids love this Gecko Run set. It keeps them entertained for hours upon hours. The only thing I didn't like about it was that the ball would jump off the track. Besides that, it was very easy to put together and fun to play with
