    Best battery power lights on the market
    These light are great, easy to use just pull apart then wrap around the umbrella pole, holds on securely where you want it, provides 3 light setting, bright light. When done with the lights either turn them off or remove the batteries and store them away for the next time. Set of 2 lights. Great buy.

    Good, but use batteries
    These work good, very bright lights. But I wish I would have gotten the solar ones. These take batteries and I don't want to keep buying batteries.

    A lovely gentle cleanser - good for rosacea-prone skin
    I have also purchased the Thayer's Milky toner and really liked it. I normally use oil-based cleansers, like Beauty of Joseon ginseng oil cleanser (which I still do love), and Cosrx makes a snail mucin cleanser that I use for cleansing off makeup or sunscreen and it's very nice. But for my daily regular wash, particularly in the morning, I like a very gentle easy-to-wash-off cleanser that hydrates and soothes. This Thayer's has no perfumes/fragrances! Good for rosacea-prone skin. Hydrates and soothes very well. It didn't strip my skin, wasn't oily at all (though good oil-based cleansers do feel oily they don't stay oily), and felt wonderful as I cleansed my skin - also washed away very easily and quickly; I do about 14 or so splashes of water to be sure all is removed then use a washable reusable toner pad with toner to remove any lingering residue. It doesn't make my skin feel tight or dry. It is gentle. It doesn't lather up, which I like since I don't use lathering products or soaps on my face. No burning, itching, redness, or any irritation at all. I normally use K-Beauty but Thayer's is one brand I will use that's not in the K-Beauty products category. It really is a lovely cleanser.

    Gentle, Hydrating Cleanser That Doesn’t Strip My Skin
    I’ve been really enjoying this cleanser so far. The formula feels lightweight, creamy, and hydrating without leaving behind any heavy residue. I especially love that it’s fragrance free and sulfate free because it feels very gentle on my skin and doesn’t leave my face feeling stripped, tight, or dry after washing. The ingredients are a huge plus for me, especially the snow mushroom and hyaluronic acid. My skin feels soft, balanced, and hydrated after every use. I’ve also noticed my skin looking healthier overall since adding this into my routine. Another feature I appreciate is the locking pump, which makes it convenient for travel or storing without worrying about leaks. Overall, this feels like a high-quality everyday cleanser and I’ll definitely continue using it.
