So we've been supplying silicone for various industrial and research applicaion for years, and what we've found is that a full articulated skeleton at this weight—roughly 35kg—makes a noticeable difference in handling versus lighter, less balanced alternatives; it distributes the mass better, lets you pose it naturally without fighting the frame.
Sometimes you don't realize until after you get it that the medical-grade silicone needs a specialized cleaning kit, not just soap and water—most people think they can wing it, but porous surfce makes it tricky, and if you're not drying it properly you'll see it degrade faster than expected. 3. Honestly, the 16-18cm depth is pretty standerd for this size at 169cm, but what stands out is how the internal texture mimics the real thing closely enough to make a difference in use—it's actually better than some high-end brands we've tested against, though we're biased. 4. It's not meant for constant heavy action every day without maintenance, I'll be straight with you—the silicone will hold up, but teh joints need to be reset occasionally.
