Yes, Elixir's are awful. The go dead in minutes and they break much more readily than most other strings!

That said, I bought a second hand Santa Cruz nearly two years ago which had a set of light gauge Nanowebs and they're still on it - the same set! None of them has broken, I've not been particularly gentle with them and they still sound fine. I've decided to change them several times but on picking up the guitar found that the ones on it are still fine.

I definitely can't say this about any other strings I've ever used and I've tried and, trust me, I have several guitars and I've tried quite a few types of string over the last 40 years.
