I removed all of this flash using nail clippers and the performance improved noticeably. Each and every one had a bit of extra plastic where there shouldn't be any plastic, causing catching issues. The biggest issue with this puzzle in my eyes is the flash on the + centers. The puzzle does have some issues with pops and lockups where pieces come out of place and sometimes these lockups kill a solve, but generally they're pretty manageable. I loosened the puzzle by a quarter turn from the factory tensions. The turning is crisp, smooth, and fairly fast with lube. The magnets are great and help a lot with turning the layers you want to turn. It's much smaller than other gigaminxes, actually only 2 or 3 mm larger than the Yuhu megaminx, but it doesn't feel too small when solving. This puzzle is by far the best currently on the market for speedsolving gigaminx. At the time of writing this review, I currently hold the world best for gigaminx with a 5:07 single.
