I've used fine lines ... Ok product, in my experience I've needed to twist and bend them a bit. One thing that I don't care for is their customer service. Every time that I have called them (3-4) times has been a less than pleasant experience. In my opinion the people that I have spoke to have been somewhat rude. When I call I have part numbers ready to go so there are no stupid questions not sure why is get that kind of treatment. It almost made me feel like I should spend my money elsewhere even if that meant getting an inferior product ...
