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

As expected. Kids love it. Good starter set

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.

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.

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

Great gift! Easy to assemble

I can't really say anything about it as it's a gift for Christmas. It looks fun.

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.
