Like so many other fools, I ignored all the reports of backs falling off, nonexistent Customer Service, and general bad business practices and ordered one of these anyway. The back fell off the thing on the FIRST day I wore it, all of my emails to Chronos (the ONLY contact information the company has) were ignored, and I’m out $100 plus shipping. I have NO complaint with The Grommet; they are a wonderful company and I’ve Never had a problem with anything I’ve ordered from them - until now. The problem is with Chronos, the crooks who make this defective product and then refuse to fix/replace it when it breaks. Don’t fall for this phony piece of junk and Grommet, PLEASE distance yourself from Chronos and drop them from your catalog!!!
We'll see how this one turns out.

I had to return my first watch adapter due to the back of it coming apart after only a few days. I got a replacement with no problem, which I greatly appreciate. The issue with this one is that so far it sometimes does not stay connected with the app and I have had to uninstall and then reinstall the app, thereby losing all previous information. I am going to see if this continues. If so, I will be returning this one as well. I really like the concept of this device because it enables me to wear my own watches. I am really hoping that it works out.
Great Concept, Poor execution

This was an exciting offering for me to try so that I could retire my Withings Activite Pop and return to my beloved classic Seiko watch. I have in short order tried this product twice, since the thin metal backplate fell off of each one at the end of the first day of wearing. The Chronos performed flawlessly while wearing during the day, yet something is obviously going wrong in the manufacturing process. One time, that I thought could easily have been a fluke, especially with a new product. Two in a row seems to me to indicate more systemic problems. It remains a great concept and I hope the company can perfect the assembly in the future.
I so want this device to work, but it's resisting my efforts.

I am an IT guy. I am on the verge of returning this device. It fits well on my watches and the micro-suction pad really holds it in place. The device or its application is buggy -- hard to say which. It disconnects from my phone for no apparent reason even in close proximity to each other. It also will alert me that the device is discharged, even though I just charged it. The only fix I have found on my Android phone is to tell the app to "Forget the Device" and then reconnect it. I have left messages on the manufacturer's website but no solutions posted. The app forced me to install an update to the wearable itself, but these issues recur. This morning, I discovered a new "trick". I got an alert for e-mail. The white LEDs came on and would not shut off until I put it in the charger. There's no way to turn the device off or to put it to sleep, it seems. Wonder if they plan an upgrade to either the device or it's phone apps?
