I just wanted to make a little review on a tankbag I bought. It's the "Daypack" made by Bags Connection (SW-Motech)
I bought the bag on Twisted Throttle with the matching tank ring.
When I got it, I realized it's smaller than I thought. It really looked bigger on the pictures. It's no big deal since it can be extended for extra storage and after installing it on the bike, I doubt I would be satisfied with a larger bag. The bag material is really sturdy and this thing smells high quality. They abviously paid attention to every detail when designing this bag!
Speaking of the installation, it required to drill four holes to accommodate the top of the tank ring device. It's no big deal since they even include the proper size drill bit and a template. Of course, if you never touched a hammer, ask a friend for help
I also got the GPS/Smartphone holder that matches the bike. It's a lot more convenient than the handlebar mounts.
If you need a smallish bag for your daily commute to work, this is the perfect thing to get. I can carry my lunch, wallet and phone without any problem. If you encounter heavy rain, there's a waterproof cover than comes with the bag.
