Let me echo Bill's sentiments above and add a few caveats.
A resin kit is not a plastic kit. There are some differences in the medium which you may need to address. Resin may warp. This may be fixed by putting the part in simmering (not boiling) water for a few minutes. Remove from the water and straighten the part, Allow to cool and proceed.
Second you may find surface bubbles. There are several approaches toward fixing them Large bubbles may need to be cut away to good material then build the piece back with some strip styrene, Bondo, and/or superglue. Small bubbles can often be fixed with a dab of Bondo or superglue.
The instructions in some of the early ISW kits were rather poor, often not much more than an exploded diagram. Later kits have much improved instructions. However a secondary reference may be required for some assembly & detail sequences.
ISW has an excellent customer relation philosophy. They want you to be satisfied. If there is something wrong with the kit when you receive it, contact them and they will replace the parts (even a whole hull). Youre building the kit, something doesn't fit, you break a piece, drill through a part or sand too much. Contact them and tell them what you did and they will fix it. I have heard stories of a cat knocking a model off the shelf years after completion. The modeler contacted ISW and they supplied replacement parts. Buy with confidence.
Full disclosure, I have worked the ISW booth in the past at IPMS conventions and I have made several of their masters.
