I had someone send a message asking how I'm like the cover and figured I would get around to positing an update here as well.
Overall, I'm happy with it. In a heavy rain or going through a car wash there is some water that makes it's way into the bed. This appears to mainly come from the tailgate at the gaps between tailgate and the edge of the rambox. I think this is an issue with the BAK products as well and probably requires another gasket or something that really has nothing to do with the cover.
I like the matte finish and it's low profile design. I had to take a loveseat to the dump the other day and the ability to quickly remove the entire roll came in handy. I was able to remove it within seconds and push the loveseat in all the way and close the tailgate. Re-installation of the roll was quick and easy as well. I could have simply tied the loveseat down with the tailgate open, but I prefer to keep the tailgate closed when possible.
Rolling the cover up and back down is quick and easy (haven't tried in freezing temps yet). It's not quite as convenient as something like a retrax (due to having to push down the velcro), but I keep it closed 90% of the time, so for me it's not a big deal. I found that in order for the weatherstrip to sit properly at the tailgate you have to unlatch the cover, close the tailgate, and then latch the cover. This is only an issue if you want to open the tailgate, toss something in the back, and close the tailgate (without opening the cover). It actually is possible to close it and then adjust the weathstrip, but to me its just quicker to unlatch, close the tailgate, and then latch. There may be some adjustments that can be made, but I haven't really looked as I would prefer a good weatherstrip cover to keep as much water out as possible.
One thing I like more about something like the retrax is the ability to lock the cover down at different positions. For me, this isn't worth the added cost and having to carry an extra key. I guess there are positives and negatives for any cover style and you just have to figure out what works best for your needs and budget.
Below is a link to a share album with some photos. Ignore the condensation on the rails. I had the cover rolled up overnight and put it back down this morning without letting the condensation burn off.
