It has mostly positives, but in less than 7 months it doesn't work. It has a problem with its case and in order for it to work even a little bit you have to hit it, but after 5 seconds it stops working because its light turns off.

It looks identical to the authentic Dell one, its features are the same and it says dell.com on it, etc. Of course, someone more astute than me couldn't help but notice that the packaging it comes in is completely no name, it doesn't have any papers inside (warranty, compliance declaration, disposal instructions, etc. that big companies usually include), and at the same time, neither the packaging nor the inner bag is sealed. Therefore, you can't be sure if the sticker was actually put on by the factory...

I bought it twice. The first one broke quite quickly. I had to buy a second one. If it breaks again, I will definitely go for something more expensive.
