You gave them good exposure. I've been thinking about lift solutions for a house I'm about to move in to. I'll most likely get a quick jack. It looks perfect for what I'll be using it for.
If I'm on a busy road such as an interstate I'll use Waze to keep me advised of police. It works incredibly well. They pretty much have no chance of sneaking up on you.
I've changed a lot of filters on cars, bikes, tractors and other equipment. I've never seen a properly installed filter loosen. They always get tighter. I attribute this to the gasket lube drying out.
