Some people think these short term health plans will be a great way to keep health insurance costs cheaper, but these short-term plans lack the ACA protections against insurance company chicanery.
Magellan on Bogleheads has a great post about this:

1) Deny claims if anything was incorrect or omitted on the application, even if the error is not intentional or material.
2) Limit max payout per year, or exclude certain types of coverage (eg hospital, outpatient, drugs)
3) Exclude coverage of some outpatient procedures or some prescription drugs.
The last one is particularly pernicious because you have to basically be a medical expert and read the policy's fine print and drug formulary to learn what's covered. Some plans cover some prescription drugs, but exclude all or most chemotherapy drugs. This can leave a 6 figure hole in your coverage even if everything else checks out."
