What customers are saying

  • Customer photo: Rechargeable LED Desk Lamp

    Bright enough for late work

    I use this desk lamp every evening. The light is even, there is no flicker, and one charge easily lasts me most of the week.

  • Customer photo: Smokeless Fire Pit

    Our patio's new favorite spot

    Lights easily and really does keep the smoke down compared to our old pit. We have used it most weekends this fall and the steel still looks good.

  • Customer photo: Cordless Handheld Vacuum

    Handy for quick cleanups

    Light, quiet enough, and great for crumbs around the kitchen and car. The battery is fine for quick jobs, not for the whole house, which I expected.

  • Customer photo: Knit Hoodie Blanket

    Ridiculously cozy

    Soft, thick, and big enough to curl up in on the couch. It has held up well after a few washes on gentle.

  • Customer photo: Elevated Pet Bed

    Our dog claimed it on day one

    Easy to put together and sturdy. He likes that it keeps him off the cold porch boards, and the mesh is simple to hose off.

  • Customer photo: Heated Blanket

    Warm and even heat

    Heats up within a few minutes and the settings are easy to use in the dark. I would have liked a slightly longer cord, but otherwise very happy.

  • Customer photo: RC Monster Truck

    A hit with our seven-year-old

    Tough little truck that has survived plenty of curb bumps. The charge lasts long enough for a good afternoon outside.

  • Customer photo: Magnetic Car Phone Mount

    Holds well, a bit bulky

    The magnet is strong and my phone has not slipped once. It sits a little far out from the vent on my car, so it is not the sleekest look.

  • Customer photo: Everyday Walking Shoes

    Comfortable from the first walk

    No break-in period for me. I ordered my usual size and the fit was right. Good support for long walks with the dog.

  • Customer photo: Solar Garden Stake Lights

    Soft glow along the flower bed

    Easy to set up, no wiring. They come on by themselves at dusk and give a warm, subtle light. A little dimmer on cloudy days.

  • Customer photo: Ceramic Space Heater

    Keeps my office comfortable

    Small but warms my home office quickly and stays quiet during calls. Easy to carry from room to room, too.

    Great for family game night

    The magnetic pieces stay put when the board gets bumped. Nicely made, and the kids actually ask to play now.

    Perfect bedside light

    Short clip of the lamp on my nightstand. The touch dimmer is smooth and the warm setting is easy on the eyes before bed.

  • Customer photo: Compact Dash Camera

    Small and out of the way

    Sits neatly behind the mirror and I barely notice it while driving. Setup took about ten minutes. Night footage is decent, not perfect.
