The LBL Designs HuDong Magnet Upgrade Kit makes your FanXin HuDong Light smoother and more flexible without compromising stability. It replaces the 8-magnet ball-core with a 20-magnet version that also has wider magnets to make the feel more consistent throughout turns. This kit also allows you to remove the foot magnets from the edges to make the cube smoother and replace them with stronger corner-edge magnets to recover the lost stability. You can apply these upgrades to any version of the HuDong, but we got the best results with the Standard version.Comes with:
20-magnet ball core
26 3x1mm magnets to add to edges
Plastic razor blade to remove edge caps
MoYu magnet adjustment tools to remove edge foot magnets

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.
