Unleash Your Creativity with the DIY Alchemy City Marble Run

The quest for cyclical perfection and infinite expansion continues with this latest marble run kit from ROKR's Parallel World Series. Infinite marble loops are possible with its node gear drive mechanical core, the mystical journey initiated by an automatic staircase module. Upon ascending, the marbles fall down the 182cm-long track with transparent channels, a crystal elevator, alchemy bottles, and a core furnace. Red crystals accentuate the path, and over 120 interactive lighting effect combinations, created by 7 groups of light boxes, entertain your eyes with orange, purple, green, and pink LEDs. In the center is the Chaos Capitol, a flickering tower connected to multiple bridges across the track. Play with all marbles, sounds, and lights activated with Sport Mode, or tone it down with only breathing light and ambient sound in Viewing Mode.The 3D puzzle kit already includes the 191-piece world module that links it to other Parallel World marble runs.

*Notes: Other marble runs and lift modules must be purchased seperately. You need to prepare 1 Type-C power cable by yourself.

Works great on many different size cans
Works great on various size cans. It is a little larger that other openers, but seems very sturdy. It is a little loud and slow, but not a large concern. Very happy with it.

Stopped working after 3 months
It stopped working after 3 months. The motor still runs the gear still turns. But it does not engage the can to cut. I bought it for a post operative situation and I am glad that it worked when for the length of time it did but it's disappointing that I now have to throw this item away.

Meh.
Worked great the first couple of times it was used. But then it stopped cutting into the cans and does not open them. It causes the metal to fray off in small pieces which resulted in getting a piece of metal stuck in my finger for weeks so I don't recommend. It's also very loud.

not better than manual……!!!!!
Do Not Buy This Product. this review is coming at 1 April 2026. This can opener was purchased in October 2025. My initial review was that it worked well and did the job. It was meant to do however, after a few uses, I noticed that the can opener continue to move around and around the can even after the can lid had been cut open. in January 2026 it began to make more and more rotations around the can and the lid was not cut loose. After a few more uses. It just rotated and did nothing else. I sent an email to the company. I contacted Amazon about it. I’ve done everything that I can possibly see to do but I get no positive results. Consequently, I have a six month old can opener. It does not work. worked well for the first 10 or 20 uses; then the cutting edge just wore out (3-4mos.), so now my money was wasted. No explanation no offer, too bad.

Don't waste money on this one
Ordered in January 2026. Worked good the first few times. Now it just rotates around and around the can but doesn't cut anything. I'm so disappointed because it failed shortly after my return window closed.
