Heather Darwall-Smith has combined her research findings, clinical expertise, and curated techniques to create a uniquely visual approach to explaining the interrelated factors that make up our sleep habits. She also provides natural techniques to deal with these underlying causes. Humans are biologically programmed to sleep, Heather encourages each of us to work out the changes we can make to our lifestyles to nourish our body clocks for us to sleep naturally again.

Great Wireless iPhone Charging Station
Color: Black
First and foremost, this is not a fast charger. It's a wireless charger, but still charges at a decent speed. If you're in a hurry and want a fast charge, use the provided cable for a direct connection to the provided charging block. If you can accept this, it's a great product that works as it should to charge your phone, watch, and ear buds simultaneously. I have an iPhone 17 Pro with an OtterBox Pro Defender case, and it charges just fine. Folds flat for travel. Seems well made and the price is reasonable. I have no complaints and would recommend this product.

Works good.
Color: White
This works good with the right phone case. The phone needs a thin case otherwise it will not charge with a thick case. It works with my iPhone 14plus. It charges the iwatch good and very convenient for having at bedside.

Versatile, comfortable and a delight to wear
Size: 10.5 Wide, Color: Army Green
Had never heard of this brand but needed a pair of waterproof boots for a trip to the PNW where we would hike in mountains, rainforest and beaches. I have a pair of Merrell Moab hiking shoes, but wanted something that covered more and were waterproof. These boots are amazing. They are one of the most comfortable shoes I own. I wore them everywhere and found I preferred them over other shoes throughout the trip. They stayed comfortable and dry no matter where we went, rivers, lakes or the ocean.
I’ve now worn them on several trips including a March trip to Bryce Canyon where we went from snow on some trails to the heat of the red rocks in others. I love these boots more every time I wear them.
I am a huge fan now. At the price they are a nobrainer. I would buy these Nortiv8 boots over and over again.

Good value for a $55 boot.
Size: 12, Color: Army Green
I like these boots because I have a wide foot and even though I bought the 12 and NOT the 12W there is plenty of width. Very comfortable boot. I have put this pair through about 1000 miles mostly on asphalt, ice and snow. Very little actual dirt/ rocky trails. I bought them for the waterproofness and ankle support. Now the soles are getting thin and I can feel small rocks through the soles. Plus the soles are beginning to separate from the uppers and they are no longer waterproof. Not bad for 1000 miles. Still, I feel For a $55 boot they are a good value. I am 6ft and weigh 250.
