The designer quoted on his website a 19 y.o. Hemiplegic man: "I have found ways to hack many routine tasks but opening a condom remains challenging. You're not supposed to use teeth and it would have been weird to ask her". Putting a condom can be a weird situation even for inexperienced young men without any motion problem, in fact the One-Handed Condom isn't a banal idea at all.
Design deal with the problems of real people and it's pretty awesome to see that even a tiny project like this can have such a positive impact in the life of someone.
