Why the negative reviews?

I really expected a buggy app based on reviews, but it works exactly as described. Push a button on the watch to connect, make settings changes in the app, send the settings to the watch. Voila! Automatic time synchronization works if your phone is nearby, but you can also sync time (and location though…) to the phone with quick push of another button. Takes 5-10 seconds, has worked for me every single time. Syncing 2 watches.

Worst Customer Support Ever

I originally bought the GBD-H1000 as I sought out a smart watch that wasn’t an Apple product. I was disappointed that it was only really designed to record running, shame on me for not doing more research.

I received a pre-order promotion for the new GBD-H2000 and was excited that it’s capability had been expanded.

I downloaded the new Casio Watches app to my phone and it immediately told me that there was a software update for this brand new watch.

I followed the instructions on the app to conduct the software upgrade. When you get to a certain point in the app, you need to scroll down the page to get to the link to update the software but the page does not scroll.

Multiple phone calls to Casio Customer Support and no one knows how to fix the problem. Every call I got transferred to a different support group and no one in the company knows who is responsible for fixing their app so that you can actually download the software upgrade.

Absolutely disgusted. I own a dozen G-Shocks and I will never purchase another.

A brand new product release and the app and software do not work properly and no one in this international company knows how to fix this problem?

All I wanted to do was update the time after a flight, and I was confronted with instructions to change to a new app. I did the data transfer as suggested, installed the new app, and.. nothing. There is nothing there. I do know that I am now constantly badgered to create an ID. I see no reason Casio needs any user information from me to support a product they have been supporting until now. Given the complete absence of data after following the instructions, I have no confidence in continuing to use this new app. Why, Casio? Why? It’s worse now, while before it was simple and elegant. What a disappointment.
