Review: Excellent - Light weight and functions are simple use
Review: Great Budget Friendly Watch - The Casio F91W is one of the best starter watches that are great for everday use (work, school, etc). This full black version of it looks AMAZING. It is notably a bit smaller than the actual Casio F91W but nontheless it looks great. I love it for its simplicity and three modes, it does everything that you need it to, without overcomplicating it. The alarm has always worked great, but I wouldn't rely on it waking you up in the morning. The stopwatch works like, well, like a stopwatch. And the actual time is great, came out of the box set up perfectly and you can switch it to 24 hours if you prefer that. The only CON that I mention is the Casio F91W uses a single green LED light on the left hand side, this in my opinion does nothing for night time checking. It is barely noticable and the camera can't even capture how bad it is. I do not deduct stars for this though, because you can still read the time in pitch black anyways. Overall, I reccomend the Casio F91W for anyone who needs an alarm, time, or stopwatch with nothing more.
