They have some real nice details put into them, and they are light weight, those are the only pros I can come up for them.
They are always always expensive. usually more than a box of the most common unit in that army. If I could find models I liked that were plastic or even metal I would buy them. I hate hate hate resin models
Maybe I am too much of hobby lightweight to get the full bang for the buck out of these models, but I would like them to get rid of the resin all together. I would like to hear from the people on this one.
One: They dont paint well, even with good base coats paint doesnt like to stick to the model. In most cases I apply a second base coat over first and sometimes have had to go back and apply a third base coat in some areas by hand, i use the spray on the first two. Colors never seem to come out right on the resin and I have even had paint come off the model, paint flaked then fell off.
Two: They are a nightmare to put together and keep together. Same problem as paint, glue doesnt seem to want to stick. I have tried crazy glue, super glue, both of GWs light and thick glue, which to be frank i wasn't surprised when they didnt work because they never do. Then when you finally put it together it breaks before any other model. I have even had pieces fall of during the night. left the model standing up after painting, in the morning wake up to paint but find first I have to re-glue an arm on. I even hold the son of a gun there for a good five minutes, and still the glue just doesnt seem to want to hold. I have even tried elmers and rubber cement, nothing seems to work.
Third: Holy cow cleaning the pieces off of the sprue, I spend a good ten minutes picking pieces off and shaving away wherever the press came together and leaves the edging going around. Yes the models look amazing when done but you have to spend too much time to get them to that point. Another thing I have never had to deal with in my 12 odd years of the hobby, my Chaos daemonic mount still had a piece of the foam die they cast the model in practically inbeded in the model, pic to follow, took me ten minutes to pick that crapper out of there. And I always miss some piece of shit sprue bit leftover until i am painting details on the model, my job requires me to spend hours looking at drawings trying to find mistakes of 1/16th of an inch or less, and yet somehow one bastard always slips through
