Not for laptops, only phones

When it said USB to HDMI I assumed it work on a laptop... Nope. It only works on my phone, which I don't like to watch TV on. I guess I have an extra charger now.

DO NOT BUY. THE PORT IS NOT STANDARD MICRO USB BUT SOME WEIRD THING WITH RIDGES.

YOU HAVE BEEN WARNED.

Nice quality cables, but definitely geared towards Android phones.  I have an iPhone and could not figure out how to make it work.  I downloaded the required app, but couldn't figure out how to connect it.  Also, there was a warning on the screen that stated that using this item with an iPhone would use data as well as wifi.  You were required to turn on your mobile hotspot for use.  At that point, I decided that I was no longer interested in using this product. I did not try this product with an android phone.

I received this item in exchange for my honest and unbiased review.

Won't charge my phone or sync the phone to my laptop.  I would not recommend these to anyone

It works ok with my laptop, but unfortunately I bought it for my Samsung S6 edge and it doesn't work.  Tried several cables and attachments, but no bueno.  Ended up returning it.

I purchased this product and couldn't get it to work on a PC, laptop, or pda (cingular 8125). Not only does it not register in any SD/MiniSD card reader, but the craftsmanship appears to be suspect as well. I am currently pursuing a refund.

Ok, I thought I could use this to connect my phones charging cord to a usb drive- but it doesn't work.  If that is your idea- don't bother sorry!
For what its supposed to do it works fine.

This product was absolutely not compatible with my blue-tooth enabled Dell laptop running BT4.0 although it did work with my iPhone. Discard the headphones immediately and replace with better headphones. The mic is not that great--phone calls sound thin and tinny to the hearer.

This doesn't work for all devices, and I believe that when we took it to Vietnam the 220 volts blew it out a bit. Still works for small electronics (phones), not for tablets.

Buyers beware. This item is for cordless phones. It has a 3/32 plug. This size is not for cell phones.

I bought this with the hope to share a PC speaker system between two sources with needing to swap connections. Unfortunately this cable only works if:

a) Only one device is plugged in, or
b) both devices plugged in are turned on

Because one device is my primary and the other is something I use on occasion only, this cable really doesn't do what it should. Unless both computers are on I get no sound through the cables until I unplug the device that is off. I looked at similar products on Amazon and saw this was a complaint on other cables, but this one was listed as working for this exact scenario. Be aware if this is what you want, this cable will not work for you.

Does not work with my work computer, and I don't know if it would work with a laptop since I only bought it for work.+

I was disappointed because I intended to use the device as a monitor on my regular telephone system. I find it is only used with cell phones

Hooked this up to a Dell desktop and an IBM T43P via docking station. Mouse doesn't work with IBM laptop, even if laptop is rebooted. Checked the manual and it says if you have an IBM or Toshiba laptop, it won't support both mouse and keyboard so use the laptop's keyboard. Yeah right!

I called customer service, which has no toll-free number, long wait time, and they eventually just said "yep, doesn't support IBM".

Wish I had sorted the reviews by "worst first" before buying, rather than relying on the overall rating.

It doesn't work with my LG G3 phone or on my Lenovo Yoga 2 Pro laptop. It could be because it was not meant to work for those products but I have no clue why they wouldn't work. That's why it gets 2 stars. Because it could be my bad.. But I doubt that.

Won't work to recharge devices if it isn't connected to my laptop. I purchased this to organize chargers for multiple devices.
