I wanted the SO but couldn't find it in Australia. I bought a free home stroller in Perth, Western Australia and replaced three of its cameras with new ones from Bunnings (aka Home Depot). I then spent the next two years fixing local leaks in the pipes. Fast forward to the last month since returning to the States. We got another free stroller that looked almost new except for flat tires and a wobbly/squeaky front hub. "Forget the new cameras," I said to myself, "I'm not doing this again!" I took a 16-ounce bottle of slime and spread half of it over the stroller's three wheels, leaving the tires inflated. No leaks! It's much cheaper and better than buying and repairing cameras.
