The Omron HR-100C Heart Rate Monitor worked for a short time when I first tested it. When I tried it the second time the receiver did not receive any signal. There was no low battery signal on the receiver (I don't know where this is supposed to appear). I opened the transmitter battery lid. The battery tested ok with a battery tester. Only problem with that was when I closed it the rubber moisture ring is stretched out of shape. The produt seemed to work fine the one time it worked.

I used it one time and it worked just fine next time I went to use it and it no longer works. Very disappointed.

It worked well the first time; then it stopped working so I went back to my USB 2.0 version.

Only worked 1st time does not work anymore, I think the contact the batteries touch is not positioned right. even the time it worked had to unscrew slightly.

This product only worked the first time I used it.  I just attempted using it again and it makes sound but the blades do not spin.  I have tried to attach and detach the blade part but it still does not work.  Unfortunately my return period ended 5 days ago! What do I do now?

It won't work after only fillng it once. I have others that work, so this seems to be a faulty product.

I was about to return it because it didn't work the first 8 or 10 times I tried it. It's the way the cord is attached on the bottom. Then, magically, it started working.

I got this to recharge the batteries for my cell phone and gps tracker while on a ten day backpack trip on the A/T. According to the specs, it should re-charge four to five times. Did fine the first time. The next night I used it again and it drained down to one charge remaining. And that charge was unable to recharge the phone. That all being said, the next time I tried it it did better. Turning the phone off while charging worked much better.

It worked fine the first time I used it.  The last few times I've tried, it won't vacuum and seal the bags.  I have cleaned the moisture from the inside of the bags, cleaned the unit, and followed the instructions to the letter and nothing works.  I even pre froze three chicken breasts before trying to vacuum seal them  (as instructions suggested) and it still didn't work.  I had an older model several years ago and it worked fine for years.  Looks like I wasted my money.

It didn't work the first time I tried but think I wasn't reading the directions correctly as when I tried it again a few days later it worked perfectly..

I bought the Pharos's 150 because of its low price and the walk mode.  It worked well for me for the first time.  The second time I used it, it had an "desination.exe" failure and told me to shut if off.  I did and was able to enter the address again.  But it turned itself off after about 20 min while I was on the way to a new place.  The unit would not turn on and I ended up spending 40 min more to ask around for directions and getting lost many times in light rain.  When I got home, I charged it overnight and it still would not turn on.  I called customer service and was told to reset the unit and it turned on.  I was told that this happened because it was a new unit and once it had been used for a while, this would not happen.  I never expected new things to not work well, my mistake!!!  I used it for a third time and everything is fine.  It does need 2-3 min to find the GPS signal (feels like 10 min).  So I gave it a 3-star because you get what you pay for.  While it works, it is good enough for me.
