    The phone came sealed as New in box. Excellent quality and well packed. Good value. Looks great. Good value for money. It was the exact model variation I wanted. I can recommend this seller. Took 14 days to deliver from China to South Australia by YunExpress. The only issue is the YunExpress tracking doesn't give an ETA.

    Overall a good seller. Only complaint is that the shipping was close to a week later from what was advertised, but the seller sold me a working phone and when I found the S-pen was not working properly sent me a new S-pen without even asking for the old one back. I can't complain about that level of service.

    Good price brand new Samsung brand phones had a few problems with the order as far as they ran out of the ones that I wanted but the seller was very prompt in letting me know and made sure that I was ok with getting what they had before they just sent it out without me knowing very good seller recommended

    Samsung has one of the best screen displays.

    My Samsung S9+ stopped working properly so I purchased the S21 Ultra as a replacement and since it's another Samsung it's familiar. Samsung displays are some of the best. Speakers are pretty good. Battery life is good, but not outstanding. I haven't used the cameras extensively yet, but they should be an improvement over my old S9+. I saved myself some bucks by buying an S21 since it's not the current generation. Overall I'm happy with the phone. I don't give it 5 stars though because like so many other phone manufacturers they took away the expandable storage and charge high prices for more internal memory. Let's me honest, internal memory isn't that expensive. I also don't care for the lack of 3.5 jack these days which is why I was hanging on to my S9+.

    there's no place for me to put a memory card it only has internal.

    Is advanced is I would assume you could put extra memory I mean it's huge and has a lot of life and it only has the standard 256 memory with no place to cook your terabyte of extra memory to your memory cards no no no I need all the memory I can get very disappointed that you're not have extra memory slot.

    S21 Ultra, Good....Battery life keeps it from great

    Battery life is ACCEPTIBLE. NOT great. Very customizable. There was no charging able included. Good size. Easy to use. The on/off button and volume are on the same side; makes screen-capture tough if yo need this feature! Not sure if it is my Wi-Fi, but this phone has a tough time moving data via Wi-Fi. Previous galaxy did not.

    Hefty phone with great performance and camera.

    Usability is the same for me since we only use Samsung S or Note phones. The camera and video recording are superb with tons of features. It's a well-built, hefty phone with plenty of battery life.
