I have had it for about 3-5 months and it has not disappointed me. I got the 128gb wifi version, but there are other options available and there is also the Tab s7+ which is bigger. I will write the positives and negatives below for you to see.
Positives:
Very beautiful screen, bright enough to be visible in sunlight, 120hz refresh rate which makes it very smooth, 2k resolution which means it can display very good image quality.
Long battery life, lasts about 19 hours with average use.
Fast charging, charges from 0% to 100% in about 2 hours. ATTENTION!!! IT CHARGES FAST ONLY WITH THE CHARGER AND CABLE IN THE BOX, OTHERWISE IT MAY CHARGE SLOWLY AND DAMAGE THE BATTERY!!!
S Pen, although I don't use it much, it is very good and does not scratch the screen.
Gaming, although I don't play heavy games much, it never lags.
Connectivity, it has wifi 6 technology which means it can support fast wifi, but BE CAREFUL IN GREECE THERE ARE NOT YET VERY FAST wifi WHICH MEANS THAT THIS FEATURE MAY BE USELESS!!! It also has very good Bluetooth. ATTENTION!!! JUST BECAUSE IT HAS GOOD Bluetooth DOES NOT MEAN THAT IT WILL WORK WELL WITH CHEAP/OLD HEADPHONES!!!
Durability, although it has hardly fallen for me, it is very durable, but be careful not to lose the S Pen if it falls, that's why there is a function in the settings that makes the tablet vibrate if the pen falls and you move away.
Negatives:
Weight, it is so heavy (for me) that I cannot hold it with one hand.
EDIT: It does not have a headphone jack.
EDIT 2: It is not worth 720€ (it is worth 500€).
(I couldn't find any other negatives to write at the moment)
I hope my review was helpful to you and helped you with your purchase :)
