Example Input: I wanted to work my way through most of these assorted coffees before I posted my experience ... and I would bet that 60 to 70 percent of my cups have had bad, old, expired coffee! I have simply been pouring out most of the cups because of the awful taste. I will not order this again.
Example Output: 1

Example Input: This battery case is big but not too big, it still fits in the hand well. It's made very well and has a soft feel finish. I can see myself using it as a daily case to get extra battery life. It uses the lightning charger just like the iPhone so that's convient. A+ case. Really like it
Example Output: 5

Example Input: I bought both front and rear flip open covers. I gave it only a 4 star because of the rubber part. Don't know or feel it will last long term... we'll see. These are Trijicon specific... meaning they are from and for Trijicon. Which I wad glade to see. Dont believe they will work on another manufacturers scope. They are made of rubber and plastic. The door/cover is plastic... and the mount to scope is somewhat a stretch fit. It is tight when installed and you must align the holes onto scope. Protecting your weapons sight lenses are important... you know why, especially Trijicon's they don't run cheep.
