Review (4/5): Easy to Use
This is one of the easiest STP devices I have purchased. I would suggest trying it in the shower first, and then standing to pee. Simply position the wider end near your urethral opening and let nature run its course. Remember to shake it off after to remove any excess urine and sterilize it regularly. I haven't had any issues with backflow, but have used other STP devices that proved disastrous.
