Lpsventures

I have the Backflip F1 (Supposedly their top of the line). It has leaked from day 1. (Dec/13) Numerous complaints to the dealer as they sold and installed it. Finally they have agreed to warranty it and replace it. They are offering me another F1 or the new Revolver X2 Hard Rolling Cover. Not sure on which one to take. The nice thing about the Rolling cover is there are no seams/hinges in the middle. I know there may always be some leaks, but I want the one with the least amount. Or do I look at another brand. Any thoughts or comments appreciated!
