Works well with my smartphone

I use this with my phone (an HTC One V). It's great for adding storage onto my phone, and I don't need a ton extra. The phone comes with so little on-board storage though, so you need a card.

I really only use it for apps and photos (and I have a lot of photos on my phone), so I don't know how much music or video you could hold on this. Probably quite a bit a music, but not your entire library. I've never run out of storage on the card.

I haven't had any issues with this card, it works as expected.

I use it on a daily basis on my smartphone, and it works fine amazingly.

Very easy to use and set up with my new smartphone.  I like that the power is a switch instead of just holding a button.  The reason I gave it a four is that I wish it could be a little louder.  No comfort issues with the clear earpiece.

I've been using this to play music from my phone in my car for a few weeks now with no problems whatsoever.

Use with my galaxy note 5 and wife Iphone 6S (with adapter) Works well, only complain is for my own fault should have order a larger charger.
With today's large phones is hard sometimes to find the right placement once found it will charge with no issues.

Great way to manage sound on a smartphone used for live casting.  Price is excellent.  The switches are a bit sketchy; we'll see how it's doing after a few more uses.  I'd buy it again if it breaks.

I got this because it will work with my Android (a normal lavalier has 3 contacts, this one has 4). I've used it to record multiple times now, and it works fine. Comes with a nice pouch for storage while travelling. The clip fits well on my polo-style shirt collars. I'm a tall guy, but it's got a long enough cable to go from my neck to my pocket, with slack to spare.

This solution works well with my phone. It is a good, convenient size, and fits in my pocket if need be. My goal is to protect, carry, make my smart phone available as needed.

Bought this exclusively to d/l spotify playlists and put my own MP3s on it. Works great. So nice to be able to listen to playlists in the car and still have my phone available. 100 dollars cheaper than an iPod, I have been very happy with this for the two months I've had it. Although, Disclaimer: I have no idea how this would be as an actual smartphone as that is what it is. I have not once even inserted my SIM card.

While using this selfie stick with my Kyocera smartphone, I haven't had any issues. It connected quickly and easily via USB and takes pictures immediately upon pressing the button. I like that it charges via USB and not via a battery (like some selfie sticks). It charges fast and doesn't need to be charged that often. Of course, I don't use it that often either (a couple times a week), so I'm sure that has something to do with it.

It extends a good distance, holds my phone tightly, has a nice handle that is easy to grip and comfortable to hold, and can be easily adjusted to an appropriate angle. The shutter button is built into the handle, so you can't remove it like with some selfie sticks.

I do have to use a special "selfie" camera app with this because my default camera does not allow me to use the volume button to take pictures. If you have issues with the shutter button not taking pictures, you probably just need another camera app. I think this is a well-made selfie stick that performs well and can hold up well to regular usage.

I received this product complimentary in exchange for my honest, unbiased review. All opinions are 100% mine.

I got this for my cellphone and it has worked great. No problems with it. I did some research before buying but this is the cheapest deal I found. I am pleased with my purchase.

Pairs up easily with my smartphone.  Sounds clear and picks up talking fine.  I can get the voice command to work through my Andriod smartphone but not via this speakerphone.

I get this 6 days ago, It so far works really well with my phone.  comes with a Micro USB cable, but I was able to just plug it into an existing cable I already had plugged into the wall and it worked just fine. The small light on the front is red when the phone is not in place and green while charging. The light does not appear to be excessively bright and I think my phone will cover it at night so the light shouldn't be too bright on my bedside table. The phone did not make any noise when I reached 100% charge.
I believe that may be different phone models may cause different charging speeds,Because it is equipped with different receiver in cell phones,Samsung phone is charging faster than other mobile phone.
The end,Thanks for the seller to send this free item to me, I'll buy another from seller.
