I've had the Bak Flip G2 aluminium for almost a year. It is flat out awesome. The problems they had with the G1 have been fixed. I did have one problem that took 5 minutes to fix. The pull cord used to unlock on of the cover section broke free from the fastner. I grabed a pair of pliers, put the cord into the fastner and crimped it down again. Eight monthly later, it is still holding. The Bak Flip isn't 100% watertight, but it is pretty close. Water comes in at the corners of the tailgate. The G2 is sturdy, makes the truck look great and is highly functional. Just last night I needed to haul a stove home. I flipped the cover up in about 5 seconds, loaded the stove and off I went. If I were to buy a cover again, I'd buy the G2 without hesitation. Good luck.
