I bought these pre made coils and 1 out of every 3 breaks when pulsed. Is it me or the coil?
I keep breaking my legs!

Are they kanthal? How much power are you using and for how long? May be show a picture of one where that happened. May be you're melting them by hitting them too hard.
Yes, they are kanthal. I pulse at 10 w for about 5 seconds and one leg broke. I already threw away the coil so I don't have a pic right now
Unfortunately, in this case, it's you. You're pulsing too long or at too high a wattage. For pulsing, drop the power down to around 2/3 what you vape at, and get all the hot spots out. Pulses, when starting, should be under 2 seconds.
These aren't NR-R-NR coils, are they?

I think you are pulsing too long....lol... pulse means around 1 - sec. 5 seconds is a little long for pulsing--imo.
Of course, that just means your performance will be good, right? Break a leg? Get it?

Well, I bought them off of eBay and they just said pre-wound coils.(I just looked at the listing again)so I'm only assuming they're kanthal . However, Its worth noting that I rarely have this problem with my 316 L and kanthal coils that I make.
But under 2 seconds is good to know!
I wonder of it is real cheap quality wire is fortunately haven't had that problem even with longer pulses

When you're as funny looking as I am, ya gotta...

That's what I'm thinking. Cheap-o stuff. However, with me, it is very highly likely it's operator error[emoji4]
It's possible but I pulse mine for 4 seconds or so and never had an issue and that's off of my FT bought coils

I don't buy from ebay anymore. Just so chancie. In the past I have had mostly good results, but coils are made of metal for the quality of the metal. Kinda like batteries, I stick to what people said here.
Over tightening the screws on the atty could cut the legs or make them weak, especially if they break right at the post(s)..just a thought

Are you Sure it isn't the Post Screws crimping the Legs?
I had a RDA once (who meet with an Untimely Demise with a Ball Peen Hammer) that would crimp the Coil Legs when the Deck Screws were tightened more than just Snug Tight.
If you're using pre wound coils they're probably made of cheap metal too.
There's no point in getting them any hotter than what's needed to get out the hotspots.
I pulse at 30w for 10 seconds to a few minutes on big builds like this:
For simple coils 5w is usually enough.
