Only issue is the light feature activation sucks. Sometimes I have to tap over and over. Button would be better.
The app asks to rate it too often. I often try to observe some information on the application: but then it annoy me by asking to rate the app every five seconds.
The watch is great and the battery life is amazing. I would have given it 5 stars except for the mineral crystal!! It should ha e been a sapphire crystal like all regular Citizen watches. The mineral crystal scratches very easily and cheapens an otherwise amazing smart watch.
I have had nothing but citizen watches for 15 years and I loved them. After the last two watches I purchased from Citizen, these will be the last. The service is great, your engineers should apply for work at Disney. The Smart watch is a joke.
