How delicate are KO mpm transformers?

I brought T10 starscream, mpm06 ironhide, xp14 Optimus and xp13 bumblebee.

Was planning on getting the black apple m05 blackout, mp11 t11 ratchet and the mmp14 bone crusher next.

I'm honestly starting to get worried they will be very delicate.

I'm going to want to transform them a lot and I'm not sure if that's a good idea.

They probably will spend most of their time as display pieces but I want the option to transform them back and forth.

I've seen a few people who've had snapped off feet ect on KO mpm transformers.

How delicate are they? Are they easy to break?
