Maru Core Magnetic DIY Kit for TengYun V1
This Maru Core Magnetic DIY Kit will convert your TengYun V1 to a core magnetic version! This kit adds magnets to the base of your corners as well as around the core. This gives the puzzle a more pronounced magnetic feel with added stability.
You will need superglue for installation.

Our Promise to You
All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.
Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.
The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

The core is very easy to install, the corners are a little touchy but not too hard to allign. I had a small slip and got a bit of super glue on one of the outside faces which has permanently fogged it, but that's just a me problem, go slow and be careful and you shouldn't have issues.
I like the slightly increased magnetic feel this provides, but it also feels like the way it pulls on the pieces can cause an audible squeaking/creaking that's noticable considering how quiet the Tengyun V1 normally is.
I had high hopes for this kit, and I bought a Tengyun v1 just to install it on. On this kit, compared to others I have installed, the corner magnets orientation was not obvious. Please see the Cubicle's video on all 5 of these Maru kits. What happened with the WRM kit is what happened to mine, with reversed magnet polarity. Unfortunately this video was not out before I tried my install, and I ended up ruining a brand new Tengyun V1. Please test the polarity on every corner magnet to the core before you glue anything to avoid making my mistake! I was able to remove the corner magnets with force and nail polish remover, but I bent/damaged the corner stalks enough that the cube feels nothing like a smooth and buttery Tengyun. I would give this a lower rating, but after watching The Cubicles video honestly I do want to feel what this would be like properly installed and will probably buy both a new Tengyun and kit to try this over again. Be smart and check your polarity before you glue anything!
