Works well sometimes...sometimes not so much

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

Works most of the time, but they have occasionally lost connection with my device.  If not for these few glitches I would give them 5 stars.

I have mixed opinions on this monitor...on one hand, it works pretty much "as advertised", and since it has all the typical Windows AND Mac keys on a single device, it's great for those of us that need to run both systems. Battery life is about the same as I get from an Apple Wireless keyboard, and I've had no trouble pairing with several different computers.

On the other hand, there are a few other issues that leave me less impressed. For one, the repeat rate seems a little erratic - sometimes it works as expected, but if you're a quick typist, sometimes it seems to get "stuck". But durability is my big complaint - after not even a year, the "A", "S", "D" and "E" have worn off completely (the keys still work fine, but they are now blank). I spend a lot of hours at the keyboard, but I've never seen another keyboard that just had the letters wear off.

Otherwise, this is a unique product - if you don't mind relabeling the keys with a Sharpie once in a while, it might be a good choice.

It provides useful insight into which charger works better than another, and why, but it's also a bit frustrating.

Plug two devices into it and nothing will charge...  Hmm.  Try a different port and only one device charges.  Go back to the original USB port, and suddenly both devices are charging...  The cables I'm using might be wearing out and partly to blame. Either way, this makes testing take quite a bit longer, as you've gotta keep retrying to see if this meter is just flaking out on you, or if the numbers are for real.

It works well enough to tell me which car chargers are providing higher power than others, which keep their voltage high enough with two phones charging, and which do not.  It's a little bit more time-consuming than something better, but I've more than got my money's worth out of it.

I bought this product to use with my iPod, mainly at the gym.  Has a pretty good usage-life before needing recharged.  At first, it connected up with my transmitter fairly well.  Lately, I've had troubles with it.  Devices that have one button which is meant to do everything seem to be the most complicated devices.  I turn on my iPod, pause it, connect the transmitter, and sometimes the headphones connect up smoothly, sometimes it takes a lot of fussing to get them to connect.  I don't know if there is other Bluetooth interference or if they just aren't charged up enough...not enough information from the device to really know.  Once they are connected, they work great.  Having no wires is wonderful for someone like me, who otherwise would find a way to get tangled up in wires during a workout.  It's just initially getting connected that can be a problem and is quite frustrating.  I just want to get on with my workout and not spend 10 minutes trying to get my headphones to work properly.  I can't say they're worth the money I spent, but I do enjoy having them...when they want to work.

When it works, it is flawless. The problem is that it frequently doesn't work. Initially was laggy, but once I solved the driver issue, all's good. Random disconnects all the time and this one seems it is a hardware problem with the mouse itself. Takes about 30 sec to reconnect. I really wanted this to work, but 30second random breaks are not a feature, but a bug.

Works,  but has issues....
Sometimes it works OK. ..
Sometimes it blinks. .
Maybe I got a stinker....

Works well most of the time.  For some reason it goes offline every once in a while, which is inconvenient since I work from home.

Okay, so I'm in a quandary with this review.  It is incredibly handy, no doubt.  However, every so often, some of the outlets stop working.  I have not been able to figure it out because then they start up again.  Very inconsistent performance...hence the three stars.

Works well, but it's a little less powerful than I expected.

When it works, it's great. The bluetooth connectivity seems to be touchy and is random. Some days it'll tell me another computer is using the machine, but I'm the only one around to use it.  Other days it tells me that it can't find the printer, where as, hours later, it'll print just fine.  It's frustrating when you have to plugin it in directly and you're in a hurry, but other than that, it does its job!  The scan to computer feature works like a charm, everytime.

Works well most of the time.  Sometimes, even though my smartphone is in my hand, the app says, "out of range".  Usually bumping it on the doorknob is enough.  But a couple of times, I have had to re-enter my password to get it going again.  The key fob has worked well every time.

Does not seem to work very well.  Could be my application

Works great when working. For some reason, the two I have sometimes they work sometimes they don't.

It does do as advertised, but some receivers can't handle the weakened signal. Some of my receivers work fine, but one doesn't unless it has a full strength, unsplit signal.

As cheap as it is, it's worth having in your bag of tricks, but I wouldn't rely on it.

works fairly well, drops signal occasionally as well as being unable to handle more than two devices at a time.

Works, but takes a few ears to get the knack of using it.
