I'll say this for their quality, what you see when you preorder is generally what you get but with a softer detail in most faces.
That notion that 'this is just a prototype' seems laughable because hot toys rarely improves a figure in a meaningful way.
They bragged about improving wen-wu and I wasnt even sure what they did. When people complained about gladiator hulk knees, they improved the hairline on a figure most will just use the helmet with. People complained about the height of the IM mk 1 2.0 from the very beginning, 10 years later with 3.0 they give us meaningless die cast and a usb powered fan nobody even asked for. Seriously the height was the only reason to make another of those.
They still make cool toys, but you are are certainly paying for what you get. And the quality has certainly slipped. They used to hit homerun after homerun. When they started the awful PERS stuff that started to change.
