“The entire coat, including the hood and pockets, is fleece-lined. You can also close it by buttons or zipper.

She also loves the jewel-tone color: “The first time I wore it […] four separate people told me how much they loved it. The colors are saturated and it feels far more expensive to the touch than it is.”

“The vacuum does an excellent job on the hardwood floors, even sucking up debris from the crevices,” says Deputy Editor Anne Fritz. “I found it to be about 80% effective when it came to picking up dog hairs from carpet and upholstery (but, to be fair, I’ve yet to find a vacuum that picks up 100% of pet hair).”

Final verdict on Nori Press

Nori Press

Sale price: $89.99 | Original price: $119.99 | Savings: 25%

The Nori Press has gotten lots of internet attention, and for good reason. This hair straightener-esque portable iron is one of our favorite ways to keep clothes looking neat while traveling—no ironing board required. It’s only a little over a pound, but it doesn’t skimp on functionality. Think: six fabric-specific heat settings in addition to a steam setting, elongated arms to reach the entire width of the garment and simultaneous front and back steaming because of the clamp design.

“Not only does it de-wrinkle garments in record time,” says tester Nancy Snyder in her Nori Press review, “but it comes in handy when you want to mimic the crisp, clean lines achieved at the dry cleaner.”

During Prime Big Deal Days, the Nori Press is 25% off!

After using the Bug Bite Thing on her daughter’s fresh mosquito bites, our tester Bryce Gruber said, “Within minutes my daughter stopped complaining about them. The device appeared to alleviate the symptoms. It still took two or three days for the bites to fully clear up, but the irritation seemed to dissipate within minutes.”

“In the past, my daughter lost sleep over itchy bug bites, scratching them to the point that little scabs formed. The Bug Bite thing genuinely solved that problem,” Gruber goes on in her Bug Bite Thing review. “I think these should be required packing gear for overnight camps.”
