Funny how a half-cent (if that) part is the most important and also most potentially damaging part on a saw. Also funny is how many different wrong methods we use to install em and how many failures occur as a result..., along with how the clip is always to blame, not the installation method. And unless one very carefully measures and compares clips in a mix and match approach, well..., the odds are against the same quality spring steel from clip to clip, let alone correct dimensions between different clips and grooves..., and that goes for OEM clips in AM pistons.
As for cheap-ass AM kits, you get what you pay for (and deserve) and are taking your chances all the way around there, not just with the clips.
FWIW, I've never had an AM clip fail. My only clip failure was OEM and was my fault.
