As a specialist in USB cables at low cost, I can tell you that there is not as thin as I thought when I see the sales picture. I also you attached the photo of my article to allow you to compare, after, that does not necessarily mean you will get the same as me.
In terms of design, micro-USB male part seems very solid, the metal part is not playing with plastic and that's good. The plastic looks solid and I did not notice any degradation after one month of regular use.
Continue on the design, the USB female part, one can not expect a high quality of this kind of product in this price range, but still, note that you can not push your USB entirely, despite that the connection is good. Otherwise, the plastic is slightly thinner there, and therefore less resistant at first. If you pinch the socket between her fingers, we can "press" and plastic bends, I will not force it is not the goal of breaking the product.
Last form of advice, I do not recommend, as with any electronic product, I leave it in the sun, kind on the windowsill, it will say, but yes, nobody does it ... think again, it are many people who do not take care of it as their material. Indeed, for this small piece of wire, plastic of the socket will harden (in my opinion) and become brittle with time ... At home, I put all my cables in a box without forcing them, for example j 'avoids bend my cables in the case of this cable, although it is "a little" soft, short cables do not like strong folds, because yes, a USB cable, it's late, and it finally breaking the connections or even the cable into its sheath, and then we complain that it no longer works ...
Finally, if you know so caring, and you have a digital tablet or a smartphone equipped with a micro-USB OTG, I tested several materials, two types of tablets and smartphones 3, bottom of range as high-end, well, it works without any worry, the connection is no need to force or having to tamper with the cable, just think to have an application to get your documents in your USB drive. it also works for several types of USB key, new or old, for against, to external hard drives, I have not tested, and I will not be testing, it is not, I think the purpose, more you will unload your tablet or smartphone super fast, unless you have an SSD as self-powered external drive. If you buy such a short cable is to keep some mobility (this is my opinion, and it is only my opinion).
Finally, if, like me, you like cheap products, you are not in a hurry to receive it, and you do not always want to pay shipping costs for a breast, but you need it (with the used), this product is really for you.
