Gecko Run Marble Run Deluxe Starter Set by Thames & Kosmos – Vertical Marble Run w/Flexible Tracks, Loop & Trampoline Tricks, Fast, No-Mess Setup, Residue-Free Nano-Adhesive Pads for Creative Play

Huge hit in our house. Easy to use, removes from the wall with no damage. Lots of fun!

A fun product! Kid friendly. Easy to use. Great price

It's a fantastic concept and absolutely amazing plastic parts. Unfortunately the sticky pads fall short on the sticky part. They only seem to stick to glass and absolutely flat metal or like a white board. If you plan on building a run on your bedroom wall or down the hallway you'll need to order different sticky pads. I recommend double sided sticky pads on Amazon. I used double sided tape to build my run. I got this for my nephews for Christmas and wanted to make sure the sticky pads would work. Glad I tried it before they did.

As expected. Kids love it. Good starter set

Bought this for my (almost 7-year-old son) in October for Christmas, he was so excited when he opened it. Once we started setting it up, none of the 'sticker pads' were sticky at all. Nothing stayed on the wall, nothing worked, it was a huge disappointment. Since we're past the Amazon return window (shame on me for buying Christmas presents in October), now we have to donate it to our local Facebook free page in hopes someone can, "make it work". $25 down the drain and a disappointed 7-year-old. Thanks.

This is just the coolest toy. My son wanted a marble run but of course I couldn’t just get a dinky normal one. I found this and knew it was the way to go! Endless possibilities and configurations. This is probably best for kids aged 7 and up. I honestly think older kids would like this too. There are easy ways to create marble runs but there are a lot of difficult pieces that take trial and error that bigger kids would like to explore. The pieces have always “stuck” well for us. This toy is a top buy! Love the innovation.

Kids seemed to like it for a little bit. Harder than you would expect to do. Does not stick to textured walls.

Bought this item after my son saw it in the Amazon catalog for Christmas. Would love to return but the window closed because he didn’t get it until Christmas and the window was very short. The removable sticker pads that can be reused that are used to hold the pieces in place aren’t very good. The funnel requires 2 stickers and no matter how many times I tried, it will not stay up. The track pieces mostly stay up but the other pieces are kinda pointless and don’t stay up well at all. Any appliance you use has to be completely smooth, so if yours had any texture at all, it will not work. For me, it’s not worth the price point and am disappointed I didn’t do more research first on this product. Wishing I could return. I ended up buying a magnetic one instead from a different brand and will be trying that instead.

My son is obsessed with marble runs but they normally take up a lot of room. This is great though as it fastens to a window (or wall). The parts are robust enough for shall we say not the most delicate of handling and has allowed him to create many courses that can stay in situ without cluttering the room. He found it easy to put together, and was a good present at the right price point.

Just right for the granddaughter.
