He's OK. Not great, not bad. Looks OK, transformation is pretty average, but poseability is pretty poor. Unless you're a diehard completist, diehard Bayverse fan, or really really want a TF with a zombie-Einstein-esque headsculpt he's definitely not worth the prices he's apparently going for online.
Only really noteworthy point is that the weapons are nice, what with looking like tools - even the spear looks like a giant scalpel.
