Works okay if you have "hands free" but the length of the cord is too short to hold your phone to your ear.  The uncoiled cord length may be 3.9 ft but stretched tightly the practical length is only about 2.5 ft and relaxed is only about 1 foot.

This is a nifty little gadget for radio geeks.  It works well, but if you want to have the microphone on your wrist, the cable is a little too short.  It is possible to do, but not very comfortable.  The cable needs to be about 6 inches longer.

Works fine most of the time and holds a charge well.  I wish the power cord was longer, although the headset doesn't fall off the charger even when it's hanging down from an electrical outlet.  I have trouble keeping it on my (smallish) ear.  Every once in a while it won't work and I have to reset it.  The sound is good.  I am constantly accidentally turning it off when trying to put it on my ear because of where the on/off button is located.  Make sure the long piece you speak into is pointed toward your mouth so the person you're talking to can hear you. All in all this is a good bluetooth, and I wouldn't be without one because of the convenience of hands-free talking on my cell phone.

Despite another reviewer's claims, this does not work with phones which have power connection on the bottom of the phone.  I assumed from that review that there was accommodation for the cord in between the hands to the bottom of the phone, but there just isn't.  Thus, the cord will not allow the phone to rest in the hands in "portait" mode.  Though it would work great in "landscape," that's not what I want.

Another problem is the size...I have a big phone (galaxy nexus) and my phone is a little too big for this holder.  If placed in the hands in portrait mode, touching the screen near the top causes the phone to move as the center of gravity of the phone is higher than most phones.

Bottom line:  this might be great for average-sized phones with power connections on the side, but not so much for big phones with power connections on the bottom.

This mount is great for staying out of the way when I'm not mounting my phone (which is the majority of the time). It works fine with my phone, but since my phone (a Galaxy Note 3) is the largest it can accommodate, I can't simply pop the phone in one-handed; it takes some doing (and takes both hands).

Very nice cable, but I didn't consider that the head is quite long. This is good for easy gripping, but not for some flat screen TVs mounted to a wall. For now, I'm using the Amazon tilt mount. The cable head barely fits, but that's because the Amazon mount (though very nice and sturdy) is not that close to the wall.

Another issue which you may have is that all the connections in the back of my TV (LG 60PK950) are at the bottom of the screen (they are not recessed much). With the tilt mount, that means the connectors are where you want the TV to hug the wall (at the bottom). The connector placement makes it more convenient for access without a ladder, but it's not great for slim profile tilt mounts.

I've added a "short head" to my list of requirements for future cables.

useful with the handsfree.  I used with my motorcycle helmet, the only thing is the headset would dislodge a little with the helmet on.  radios work fine.

I just wish this was the longer of the two cables I bought.  It plugs a little too tight into my Phillips radio and older Samsung cell phone but it does what it is designed to do.  I can play music through the radio speakers and it charges at the same time.  Wish it was 8-10 inches long.  Six inches is just barely long enough.

I wish there was something between 4" and 3'. I bought the 4" to use in the car, connected to the stereo, and it is nice to keep things simple without cords getting tangle everywhere. My phone connects to the USB and slips into the cubby space just below nicely. Could a few more inches though.

This works just fine but the cord is barely 2 feet long.  i had to get an extension for it to stretch to thge outlet.  Since I was looking for extension cords I didn't actually see the fact that it was so short.  Aside from that, it works.

I like it except for the short length 3 ft just doesn't cut it. Otherwise it's  perfect for my connection to the Garmin unit.

Handy for when you need the extra length but for some reason it didn't allow me to use one of my phones while plugged in

This does exactly what I ordered it for - allows me to talk hands free while driving.  The only reason I did not give it 5 stars is that it a) can be difficult to remove at times and b) can make it so your phone gets in the way if you have short legs like I do.  All in all this item works great and offers an alternative hands free option.  Well worth the low-cost investment!

It works fine but the connector is about twice as long as it needs to be so the adapter does not fit flush with the bottom of the phone.  I need to come up with something that will fill that gap before I will feel comfortable using it on my alarm clock.

Works okay, but sometimes there is a lot of feedback or something like that, and I didn't have that before. Sometimes my husband has to remove from the cradle so he can talk without interference.  But they work great as far as  holding the phone on there, and they are very convenient.

This is a handy little charger.  It is designed to be carried on a keychain but personally I find it is too long to really work on an actual key chain.  However the ring can be attached to other things - for example, the handle of a purse, schoolbag, or a loop on a visor in the car - so that it is able to be kept handily wherever it may be needed.

It does work fine to charge the device.  However it is as short as the picture shows - there is no pull out cable.  So it really does have to sit directly out from the USB port.  In my car that doesn't work well as the weight of the phone at the end of this, plugged into a USB converter in a cigarette lighter, is too much (and sticks out too far).  This limits me to using it on my laptop.  But even then, when the laptop is on my LAP, I feel there is too much weight to attach a phone to this sticking out of a USB port.  So the only way I'd really be comfortable using it is if the laptop is sitting on a flat surface like a table top.

This limits its use in my opinion.

I therefore prefer to use regular chargers on flexible charge cables.  However I keep this in my purse to have around as an alternative should I need it.

I thought it was a little longer. Pulls out to about 2 feet.  You need to pull both sides at the same time or you could break it.  Charges the phone fine.
