This product sticks to the tank of the bike very well. I have tested in some of the bumpiest and windiest conditions I could find. It did not move even a tiny bit and never gave me a bit of concern that it would fall or scratch my brand new paint job except...
The product has steel zipper pulls to seal the compartment. While these pulls are very light, and seem to be coated in some sort of anti-scratch material, I was not willing to let them flap around in the wind and possibly scratch my tank. Some sort of guarantee from the manufacture, or at the very least they should call this out in the product description or bullet points if indeed they are scratch resistant. Easily fixed by simply snipping off the pulls with a side cutter, and adding my own left over leather zipper pulls!
The tape edge material used to attached the different parts of the product together is so thick that my standard sized droid phone does not fit very well. It would fit perfectly if they would have simply used a thinner tape edge when assembling the parts. This issue makes it difficult to use the touch screen in places because the plastic is pushed so far away from the screen.
And finally, while I do agree that every company needs to advertise their brand, putting "SHARK" in huge letters across the clear plastic cover I need to see through is not the way to get this done. This was poorly thought out, if considered at all, and makes it difficult to read the screen where this lettering is located.
Overall yhis will do the job, and it will stay put nicely, but for this amount of money it needs to be much better in my opinion.
