This particular paper is good for its price, it is double-sided Matte at 140g. It's relatively thin but doesn't lose its performance because it has a coating. If your image fades over time, it's your printer's inks to blame, not the paper. It may have a photographic coating for better resolution, less smear and protection, but it can't work miracles on its own.
The grams of paper do not directly refer to thickness; for example, glossy paper is thinner than matte at the same grams, and matte is thinner than plain paper at the same grams. This happens because the coating makes it heavier. This one reminds me in thickness of the 120-gram Navigator papers.
I bought it for a little less than €6 for 100 sheets; for thin double-sided photo paper, it's quite value for money.
------- ATTENTION: It is not for printing professional photos, it is just for better color performance in images and that's because it's matte. If you want professional images, get the glossy. If you want thicker paper, there is matte at 200 and 250 grams which is like cardboard. If your printer is dye-based, it may soak a bit, if it's pigment-based then you won't have any problem at all.
I bought it to print educational books for my nephews because the other options in matte dual are at 200 and 250 grams and are too thick (I use those for covers). I use a metal spiral and they become like notebooks.
My printer is the Epson EcoTank L850, a fantastic printer with 6 inks made for photographic quality, so the prints are better compared to regular printers and on such papers it really shows its capabilities. I have done an extensive review on that one as well (it is no longer available, replaced by the Epson L8050 for A4, and Epson L18050/L18150 for A3).
I have bought 5 from Mediarange and so far I am satisfied.

I am attaching some indicative images from an educational book I found online for free, it was in English and I translated it and print it in small notebooks for ease of use.
The cover is the dual matte 250 from Mediarange and the inner sheets are the 140 grams again from Mediarange (the product of this page).
