I prefer this type of condom over latex as they can be thinner and they transmit heat better than latex. Recently the boxes have stickers on them warning that the condoms safety vis a vis HIV transmission is unknown. Although the FDA originally approved them without full testing, the FDA later decided to pull its approval. So, we are currently awaiting full contraceptive testing results.
Quality control appears to be the real issue here.
They can also update you on their FDA approval status.
