Only works intermittently!

The refurb headset seemed good at first but it seems that the wifi cuts out about every 5 mins or so. It may be that it is just an undiagnosed issue from the refurb but there is no option to return it when I look at my orders. I think that I'm stuck with a malfunctioning headset!

Worked for a while and then starts to intermittently work.
I'm sorry I bought a second before the first one stopped working.
The same thing happens with the second.
I guess there is a reason they have so many refurbished product.

It works intermittently.  I wouldn't buy it again.  The battery life is weak.  I guess I got what I paid for.

Only works intermittently.  Resets itself too often to be reliable.  Threw it away.

It only works when it wants to.  No matter how many times I change batteries or try different soaps - it is consistently unreliable.

When it worked it was great! Only works half the time. The buttons aren't real buttons either. Wish it worked better, but I guess that's what I get for the price

I guess I received a dud.

The truck only works intermittently.  It will work fine for a few minutes, then stop entirely.  Nothing will happen.  We've tried changing the batteries, changing the frequencies (A, B, C), but nothing works.  Then suddenly, it starts working again.  Sometimes it only takes 10 seconds.  Sometimes it takes several minutes.  There's no rhyme or reason.

I've requested a replacement from Amazon.  Hopefully we'll receive one that actually works this time.

I purchased this for use on Mac OS X with PowerPoint. It works intermittently at best. Plugging in the USB and navigating through slides seems to work. But, after presenting for a period of time it simply stops working. Clicking buttons is non responsive. The only way to fix it is to pull out the USB and re-insert it back into the computer. The cycle simply repeats itself until you lose confidence in it working, and stay close to your computer to manually flip the slides.

I would not recommend this for OS X and PowerPoint. I have not test it with other operating systems / presentation software.

The first couple of times, it worked perfectly and then

Whamo.

It just stopped working and for it to work now, I have to put it in and out, in and out, wiggle it around, and once I get it connected, don't touch it! ...or it'll stop working again.

Weak!

So annoying, could not even imagine how this would work in my car while traveling.

Seems to only work about half the time. Sometimes it works well and everything is fine. Some days it will not registers cards or play any videos. Its very hit-or-miss with this card reader. I have used about 20 different cards from my game cameras, cameras, go-pro and it is always a tossup whether it will decide to read them or not

Less than a year into use and it already fails once every 10-20 min. Sometimes only components will work: Ethernet connection or visual ports will fail for 5-30 sec at a time. Super annoying when you're trying to work w/ an internet connection. The USB ports all work pretty well w/ little to no failure. Occasionally, the visual ports will stop working all together (about once daily). I won't be buying this product or from this manufacturer again.

I've had this DVD player for a few months now and it works intermittently when I try to use it.  It is very frustrating trying to get a DVD to play.  After I press the power button on and off repeatedly I might be lucky to get it to work. This is why I decided to write this review so that I can save others from this awful experience.

Sometimes it works and sometimes it doesn't ...

I can't believe all the positive reviews...  I guess I just got a bum one.  I switch it on "on" and it works but then it will periodically stop working.  The only way I can get it to work again is to slide it back to "off" and then back "on" again.  Very frustrating to have to be doing this every other slide!

This device works great when it works. Unfortunately it only works about half the time. It randomly stops working all the time. Then the next day its fine. Very frustrating considering the price. I wouldnt recommend buying this.

It is great when it works and not so much when it doesn't. I bought two units and one works fine, no complains,  but unfortunately second one did not work from the beginning - I could not make it work regardless what I did.

Works intermittently (Most of the time, doesn't work at all).  Tested on several devices.  Tried emailing the manufacturer for a replacement and was ignored.
