Is anyone else annoyed with them? I just had a bunch of gas come out of a stringtrimmer and I didn't even notice when it was happening as I was using it. And this was after I thought I had checked whether it was on tight. I've had chain oil all over the floor and have had to replace a saw cap that broke (plastic). Admittedly, you can turn the string trimmer upside down and work on it with no leaking, so when they're on tight, its cool.
