Question: How long is the chain?
Document: Very pretty, a great gift for my 9 year old daughter. But the flash drive part look very flimsy. I doubt it will last long.
It seems to be weak, but it is nice,  the size is perfect and has a chain. Good price as well.
the chain wasn't sturdy it broke fairly easily but i managed to fix it myself. but other than that it's a creative, cute USB.
It works well and it has a good amount of memory the only downfall was that it does not include the chain. Other than that, highly recommend it.
I bought two so far. The first one I bought I use for work and college. I've had it for quite a long time. Is still looks like a beautiful piece of jewelry when I place it around my neck. I bought a second one just in case they ever go out of stock.
My coleagues loved it!Works perfectly, it is not heavy and looks very cute!I wear it as a necklace or as a key chain but the purpose is obvious!I highly recommended! !
I'm pleased and it works. I did end up buying a longer chain so it would hang lower on me. I would recommend. Even received it a week sooner than they had said I would.
First of all this was supposed to come with a chain and it didn't. Secondly, the back of the heart will not stay attached to the front. Sending it back because this was purchased as a gift to put my friends wedding pictures on...I would rather give a plain flash drive than a hunk o' junk. Needless to say, save your money and time.
This is a cheap Chinese knock off made of plastic with a dog tag chain. I ordered a nice simlar one 2 years ago from amazon so I re ordered what I thought was the same one. It looks similar but the chinese tried to copy the nice version and have made this junk. It works as a flashdrive but its a cheesy plastic version not worthy as a gift.
I'm giving this two stars because although the pendant itself looks nice and like the picture (the gems are very bright for glass), it actually shipped with a super cheap looking "light bulb chain" chain (you know the kind that is like a series of small chrome balls). NOT the chain from the picture. The chain alone screams that its not intended for real jewelry and is too tacky to wear.
Answer: Didn't get the chain, it was not in my package...it fell apart as soon as I took it out of the package.  Returned it...junk. don't buy
