I installed three of these on various devices: leaf blower, chipper/shredder, and power generator. All have poorly placed plugs that would ordinarily create a mess. With the Drainzit device, oil changes are much simpler and vastly less messy. I've had no leaking issues, either. The only potential issue is securing the end so it does not interfere with normal operations. Fortunately, that has not been an issue in my case, but keep it mind, regardless.
