has anyone tried to connect them to each other to extend the length?

I think so, and it didn't work. Its junk from China, don't buy it. I went to Bestbuy to get something else not long after and on a whim checked to see if they had something like this (I needed 12 feet or so) and...right there in a back aisle for about 20 or 25 bucks was the 1 piece I needed work perfectly from Bestbuy. I bought two of these cheap on amazon...and got a piece of junk from China that the computer could "not recognize" no matter how many ways I tried it. Go to bestbuy instead and buy a reputable brand...worked for me.

your usb extension wire has a red, yellow, green and black wire inside which one is positive and which one is negative

USB wires are generally universal with the following color reference: The red wire is a positive power wire with 5 volts of DC power. The black wire is the ground wire (similar to most all electronic devices). The white wire is a "positive" data wire. The green wire is a "negative" data wire. Since the wire you have has a yellow instead of white, I would expect it to be the positive.

does it come with the plug in part, to plug the cord to the wall? thanks

No it's like an extension cord for electricity but for usb.

Does this item provide data transfer and if so what speed?

It's a simple cord I simple USB cord and I transferred data I have no idea what speed it went except to go at the speed of my specific digital items such as my phone speed or my computer speed. It is a relatively inexpensive cord so if you're looking for something high tech I wouldn't get this one necessarily but I think it could work for average everyday use.

Quality with many uses.

They are of good quality material, soft and flexible. The original USB design is more durable for extensions, and with this style you can use any type of charging, data cable to fit your device.

Pretty

Works as advertised. I'm writing this review to avoid the constant reminder to post a review. I'm so glad grocery stores don't require reviews of every product, every purchase. Display Fit Ease of use Leakage Portability

Just what I was looking for

I got these for me and my boyfriend because the outlets are too far from the bed. These made things so much easier. And I was able to keep my charging cable and just plug it into this to extend it.

Works great

Works great! As both an extender and to charge my smart band (not a fitbit). Material is solid, thick and flexible.
