Joe Rocket Hammerhead Tank Bag
Not lying about being water resistant
As others have mentioned this is not a huge storage bag. This is best used during a light travel trip (not having to carry a lot). For example, going to the park, traveling not needing a change of clothes, etc. I normally use it to carry 2 plastic water bottles, a ham and cheese sandwich, a bunch of powerbars, my wallet, and my kickstand plate. This way I have some food and water in case I need to take a break during my couple hour long fun rides. If you had to take some clothes or anything more than what I mentioned, get a proper backpack or more boxy tail bag. I also have to mention I keep the shoulder strap inside the bag as well.
The see through compartments are very handy for keeping a phone and gps but I do have to say they are SMALL. The smallest GPS on the market barely fits into the GPS compartment and I don't see myself ever really needing a see through phone compartment for the reason that it is really close to my stomach (2008 gsxr 600). Picture you are riding your bike right now, put your hands out and lean forward the proper amount... now, look at your belly button. That is how it is for me to look at the phone compartment and I don't feel comfortable looking down while riding. This is the reason I reduced the rating to 4 stars.
The very first time I went out riding with this tank bag, I encountered a HUGE downpour. I have never ridden in such a rainstorm for that long (45 minutes) and I was positive the phone was going to get wet in the compartment and break then I would lose my gps...but it didn't get 1 drop on it. There is a raincover for it but I don't think I will ever use it.
For people talking about how it closes, all you have to do is pull up (towards the sky) when pulling the zippers close. This way the velcro won't try to attach until the zippers are already almost completely closed. I have never found it to be a problem.

Decent option for holding small stuff.
I bought this because I wanted a bag with a clear pocket so I could see my phone while navigating. It works fine for that, though the clear plastic is very glossy so it can be irritating in bright sun.
This bag is decent, but takes up a lot of room on top your tank for the amount of stuff it holds. It's fine for a water bottle and sandwich, or gloves, but (at least on my bike) the curve of the tank definitely limits the total capacity of the bag.
The zippers+velcro is an awkward way of closing the main compartment; if you let the velcro close off-center then the zippers aren't lined up right so it often takes a second try to get it closed and zipped all the way.
There's also a GPS-shaped (square) clear pocket in addition to the phone-shaped (rectangular) one. I've used it to hold my wallet and coins.
The "fast access coin holder" is a complete joke, they should remove that from the description. It's a piece of elastic sewn to the outside of the bag. It can hold probably 6 or 7 coins total and I wouldn't trust them to remain there while the bike is in motion.
The magnets are strong, it never seems to budge even at highway+ speeds.

Great bag for the right bike. Good for others.
It's a bag with zippers that goes on your tank with magnets. Not much to review there, but I wanted to add a couple of comments to the existing reviews.
Two things to keep in mind:
1. This is a low profile tank bag, which means it stay out of the way of the controls, but get its volume from being long and shallow. Unfortunately, if you put the bag on a curved tank, you bend the bag over that curve and lose a lot of that volume quickly. For instance, two 20 oz Gatorade bottles will fit in this tank bag easily; they will not fit in this tank bag when attached to my bike.
2. The cell phone and GPS pockets come with foam pads stored in them to keep their shape during shipping, but these also work great to fill space in the pocket. For instance, the cell phone pocket fits my .4" thick iPhone 4 great, except it would be really far from the conductive touch-cover sitting in the bottom of the 1" deep pocket. By keeping one of the .5" pads in there, it keeps it right near the top so I can use the screen easily at stop lights. Don't throw those pads away! There are really convenient but easily overlooked!
That's about it. Otherwise, it's a great bag you won't notice 96% of the time until you need to stash some stuff.

Great Idea But Poor Execution
The Joe Rocket Hammerhead Tank Bag is best described as a tank bag with a lot of potential. The idea of the bag is great but the execution is flawed. It is a nice size tank bag for everyday use. The bag is very compact and does not interfere with any controls nor does it block your gauges. It is a good tank bag for sport bikes if you are willing to accept its flaws. I personally use it every ride to store bottled water, my cell phone, keys, wallet and bike lock. Please note that this is not meant for multi-day trips. If you are looking to pack some clothes for a long trip, you are looking at the wrong bag. Other features of the bag include a rain cover that stores in a pocket and a strap to carry it over your shoulder. The bag also has a maximum weight allowance of 5lbs.
As mentioned before this bag has some flaws that keep it from receiving a 5 star rating. The first problem is that this product fails at one of the major features, the GPS pocket. This pocket is roughly 4.25" x 4.5" x1". I have yet to see a modern GPS that will fit in here. The second issue is the cell phone pocket. This pocket is 5" x 3" x 1". If you have a smartphone you are probably out of luck. I intentionally bought this bag for these two features and sadly both pockets are too small. The dimensions of the pockets are not disclosed by Joe Rocket so I hope that this review helps anyone wondering their size. The final issue that I found with this bag is that it leaves black marks when you remove the bag from the tank. It will not damage you paint. You just need to rub it off with your finger. I guess the best way to describe it is when you have a cheap pair of shoes that leaves black marks on the floor but a quick mop cleans it right up. Overall it’s not a bad bag. I use it a lot. If you are specifically buying this bag for the GPS and cellphone pockets, check the dimensions that I mentioned above before you buy. If you just want a small bag for everyday riding to store small items and water, this bag is great.
