  1. Airmoto Cordless Air Pump and Tire Inflator
    ★ ★ ★ ★ ★
    I missing air pump 😪

    I placed an order for three (3) air pumps but only received two (2).

  2. Vornado LUCERNA 1 Alchemy Ultrasonic 0.5-Gallon Humidifier
    ★ ★ ★ ★ ★
    BEAUTIFUL HUMIDAFIER/LIGHT

    Received several hours ago and it's up and running. My only regret is I wish I had ordered a 1.5 gal size instead of this .5 gal one..But it makes a beautiful addition instead of being a large, clunky humidifier

  3. 2-Pack: Prai Beauty Meno-Soothe Serum
    ★ ★ ★ ★ ★
    PRAI MENO-SOOTHE SERUM

    This stuff is great, very cooling and soothing, I have started using the entire line. Gifted some sets for Christmas as well.
