Ever wondered how condom manufacturers ensure they don't break thus making its efficacy at a higher rate? They use the machine above, which imitates circumstances where breakage might occur.

Over a period of 7 years, broken condoms returned to a supplier (SSL, Durex) via consumer complaints were examined to determine the cause of failure. Also, some consumers who reported breakage but did not return condoms were sent a questionnaire on the causes of breakage. Finally, theories proposed for the mechanism of breakage were investigated on a laboratory coital model. RESULTS: Nearly 1000 (n=972) returned condoms made from natural rubber and polyurethane were examined. Visible features on those that were broken, were classified. Evidence combined from examining returns, questionnaire responses and the coital model strongly suggests a single predominant mechanism of failure we named "blunt puncture," where the tip of the thrusting male penis progressively stretches one part of the intact condom wall until it ultimately breaks.

Does this machine come in post as well? Because I'd like to use it to hug my gf to sleep instead so I can carry on with other things like, watch tv.
