What Is SensorSafe?

The SensorSafe 2.0 chest clip monitors your child’s well-being, sending timely alerts directly to the caregiver’s smartphone if unsafe conditions arise. Originally developed to reduce incidents of children left unattended in vehicles, SensorSafe notifies caregivers if the car is switched off with a child still buckled, if the child unbuckles themselves mid-drive, if the back seat temperature reaches an uncomfortable level, or if a break is needed due to extended seating time. The alert system extends to emergency contacts with GPS coordinates if necessary, ensuring a continuous line of protection.

Great product

Great value for the size. Easy to apply and absorbs quickly wherever you apply it. Does not leave any oily residue and it smells fragrant. Moisturizes and works quickly. Skin feels instantly smooth.

This product is da' BALM! (a softening balm that's the best moisturizer for all skin types!)
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
So many of these are all over social media and I wasn't sure to order a whipped version, or just a balm, so I went with the balm and I'm totally satisfied. No breakouts to my sensitive, mature dry skin, and the scent is light citrus and non-lingering. I suggest to lightly swirl finger tips inside the container in a circular motion and scoop a tiny amount then rub both fingertips together to warm the product as this is key to make it glide smoothly onto your skin, otherwise, you are having to re-dip into the product and use more than you will need. I use it AM/PM right after my facial serums, and follow with SPF moisturizer. I'm not a fan of foundation or powder to avoid the caked on look, but use a little creme blush when heading to work, and will dab a little concealer where needed too. I've been using my Ancestral Haven Beef Tallow/Honey Balm a couple of weeks now and my pores seem smaller than when using any of my previous French pricey skin products! I use this on my face and lightly under eyes, neck, decollete and the heels/sides of my feet every morning. Any remaining product I apply to top my hands. It absorbs quickly without being greasy. If you experience an oily result, then lighten your next application as the product is light if you don't warm it up with your fingertips. I highly recommend and can't wait to tell my dermatologist about it too! Oh and my 86 years young mom uses this daily and loves it too! (Christmas gifts coming her way so she doesn't deplete my supply - lol).

Tried 100’s of product and this is all my son lets me use on him willingly!
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
The ONLY product I can put on my child’s eczema and allergy problematic skin and not irritate his skin. My son has TERRIBLE SKIN that is EXTREMELY sensitive and to top that off, he also picks at his scabs. This is the only product I’ve ever been able to use on him and use up the entire product because he doesn’t breakout in a rash, it doesn’t sting his skin in even the worst of areas that are freshly picked scabs, and that’s a huge deal for us! It is extremely moisturizing and although slightly greasy, it’s a much better feeling on the skin then what you get from a Aquaphor or petroleum jelly. That and my son absolutely cannot stand the texture of Aquaphor and petroleum jelly, but with the tallow, he doesn’t hardly say a word as long as I don’t put it on too thick. This can be layered for extra protection in problem areas, or worked into the skin and absorbs quite nicely and feels fantastic! It has a very mild scent that I truly love, but the scent doesn’t really travel outside the jar so you know it’s very minimal. After the hundreds of products that I’ve tried and the thousands of dollars wasted over the years, I will continue to purchase this as my holy grail for my son’s extremely sensitive skin condition. Thank you so much!!!! And I will upload pictures of before and after so be sure to see how well it’s healed his skin within a week of use!

Amazing smell, awesome price, and nothing synthetic
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
This is a new staple in my skincare regimen! With no synthetic perfumes dyes, or preservatives, it smells wonderful, melts into my skin without leaving a greasy film. I use it morning and evening on my face and body, and my skin never feels dry. It leaves my skin soft and moisturized and I have this on subscription. The price is great, at about $20 for 5 Oz of nonwhipped, but soft, balm.
