This particular Kindle is subject to problems. The first one I got, new from Amazon, lasted a week. The 2nd one died a couple of months ago after about 2 years. My friend has an original Kindle from whenever they started them (6 or 7 years ago?) that one is going strong. This one just doesn't seem to be made as well.
I've used this for a couple of years. It's been with me around the world a few times. It's a rock. The only cheaper thing about it compare to original is the USB cable. They definitely saved 20 maybe 30 cents on the new one.
