I've built a few Zvezda kits and this one was a bit different from them. Instructions are better organized into sections are way more clear. Plastic felt better. Fit was better. The rubber band tracks feel odd and don't take glue to well, but the kit has track sections with link by link option. The only thing I can think of is some gaps at the bottom of the turret when you put it together, but filler can fix that.
Could have breezed through this one faster than I did, but I was building my Tamiya KV-2 and JS-2 at the same time as well. You can see my progress
