My order from Hero Forge arrived today. The plastic is slightly pliable and seems quite durable. The detail is quite good and the surfaces smooth. I judge the detail and finish to be slightly better than the best pieces being produced for Zombicide Black Plague, which for non-hard plastic models, is pretty damn good.
There are a few small remnants of tabs, here and there, but these can be trimmed away quite easily.
From a purely practical perspective, I can't say it's worth the money I paid for it, but I knew that before I placed my order. For me,the novelty of getting to create what I want has a value that is hard to put a dollar amount on. Overall, I'm pretty happy about this purchase.
I'm also relieved that my guestimation on model height was just about perfect. I set the model height at about 75% of maximum, which puts comforably it in the pulp 28mm range. Pulp scale being smaller than 28mm heroic scale (GW 40K) but larger than 28mm fine scale (GW LoTR).
