I was a little skeptical about the push fit models because the majority that games workshop sends out have gaps if you just do push fit; myphitic blighthauler, the new deathgsurd killteam etc. But these were able to get a flush fit without having to snip the pegs and use glue. They also have bases that are push fit too but don't have a se terrain on the base so you can still customize them as you want to match your army
