When my witeden 3x3x7 came, I scrambled it up and solved it normally. There was just one problem, the yellow center fell off and didn’t go back on. I later had to superglue it, which was annoying. The white center keeps popping out but I just push it back on. When I start shapeshifting the puzzle, the yellow face and the white face don’t turn well at all. It’s hard and extremely stiff. But in the end, I still really liked my 3x3x7. It was challenged and fun despite the unfortunate way it came. Buy if you want, but be warned you may need to fix it before it arrives.
