Our seats were in row 7 so we really enjoyed the Bengals/Browns game from our seats to say the least. Row 7 doesn't sound close but it's much closer to the field than you think. There were plenty of Browns fans in our section and we all gave them sh*t the entire time. The Browns locker room tunnel was right next to our seats. Only downside is not being able to read the number markers on the field at all, instead you have to rely on the jumbo tron to know where the ball is placed. There is a jumbo tron in each end zone so you will only be able to see the jumbo tron in the south end zone from these seats.
The last few rows in our section were underneath the overhang from the middle end zone level - wouldn't really benefit from this unless it's exceptionally hot or rainy. I've seen both conditions more than once for Bengals games. Got rained on really bad at the Bengals-Ravens game in 2008 and got sun burnt pretty badly at the Bengals/Buccs game in 2010.
Yes, I have a good memory.
There isn't much room for your knees in these seats which doesn't become a problem since so much of your time will be spent standing up. The end zone is what it is. Not the best seats by any means but a lot of fans will enjoy sitting this close to the action; especially if you sit in our row, row 7.

P.S. - Yes, these seats are next to the visitor's tunnel but if you want to meet some of your team's players, you will want to go to the Hilton Netherland Plaza Hotel downtown. Almost all visiting teams stay there and it's right next to fountain square downtown.
