I was psyched when I got this product and was quite happy with it for the
first 3 months (I had the blue one). Then the watch started crashing. Really
poor electronic engineering in there. Turns out, I needed a new battery. Oh,
did I mention that each time it crashed I had to reprogram the whole thing
from scratch.

About 9 months later, it crashed again and clearly was a battery issue, so
we went to the watch vendor who fixed the battery the first time, but he
was gone. The mall he was in was closing. When I needed my first battery
3 months into owning the thing, he had told us that these are very hard
batteries to come by and are not easy to get into the watch.

So here I am, 12 months of ownership and in need of a second battery. We
took it to another watch vendor and he turned us away. Then my husband
saw a younger man go behind the counter and he ran up to him and asked
if he could fix the watch. The young man said yes and my husband was
quite pleased with himself. 10 minutes later, the older gentleman called
us over. The younger man was with him. The older man said that he would
never do this again, it's a hard to find battery and very difficult to
install.

So I am happy again. I go to set the time and... no dice. From what I
could tell most of the functions were there but I could no longer do
anything with the button that put the watch in "set up time" mode. It
is now on it's way to the computer trash collection day.

I will be buying a Watchminder 3. It's unfortunate that Amazon does not
carry it, but they are on sale now at the manufacturer's web site. A word
of caution, the manufacturer's web site is collecting credit cards for
payment using an unencrypted channel. So your credit card is viewable
to anyone who is monitoring a network along the way. In this day and age,
an unencrypted web site for credit card collection is not acceptable.
I will purchase it over the phone, but I bet they will still use the
same website interface to put my credit card number into. At least it
would be only exposed on their local LAN.

I've now babbled endlessly. Sorry for the long drawn out story. Hope
you find your vibrating wrist watch that works for you.
