So much easier than fruit...
There is a reason Bell's uses juice in its cherry stout; it is easy and doesn't compromise beer quality. 16oz bottle is a great size. If you are looking for a robust cherry flavor, add the entire bottle to 5 gallons.
I used the product for my bourbon barrel aged porter. It complimented it well - I added 14ish oz to my keg before pressurizing. It had a very pronounced flavor initially, but mellowed considerably.
