Ill fitting base shaper
I'm rating this base shaper two stars because it is made of nice material and the color is very close to matching the inside of my purse. If you're considering purchasing this for a neverfull mm, please be advised that the shaper is slightly smaller than the bottom of the purse.  I contacted the seller when I received the base shaper,  thinking I got the wrong size but was advised this was the size they intended. Because it is smaller than the bottom of the bag, it causes slight bag sag.  It is not super obvious now but I believe over time it will stretch the bottom of the bag.  I've included pictures of my other neverfull mm with a base shaper, from another company, for comparison. In my opinion, this base shaper is not worth the $30. You can find a base shaper that covers the entire bottom of the bag at a lower price point elsewhere.
