    I purchased a Samsung s23 ultra phone at my local Best Buy and the clerk was Nick. He did everything possible to help me find what i needed from ordering my phone to helping me with my trade in and finally for setting up my phone. He is such a awesome employee and I hope that he is appreciated I know that I would have been lost without him helping me.

    So far the phone has been good to me. I really enjoy the camera. I do wish the sides weren't curved though because screen protectors have trouble staying.
