I've worn my Looker 2 for 10 days with no problems. My removable urethral plug extends to just past the ring.
I concur with the urination issues - but then, I have that with every device, so I always fold toilet paper over a couple of times, cup the bottom of the device with it, and then slip a cut-down-to-size plastic baggie over the whole thing. Urine isn't my only issue - after a few days being locked - and ESPECIALLY riding my motorcycle while locked, I tend to precum randomly as well. Always wearing a jock while locked keeps the baggie in place over the tissues/device and keeps all fluids from my pants. I change out the tissues any time I use the bathroom as not to keep the area moist. But it seems I've gone off topic from the Looker 2... you can see a few pics of mine in my profile.
