Frequently Asked Questions
At what age is my child ready for a belt-positioning booster like the Tanza?
The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.
Can I install the Tanza without the UAS connectors?
The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.
Is the Tanza allowed on airplanes?
Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

Such a fresh clean scent
Scent: Ocean Breeze
Such a clean fresh scent
Doesn't have all the toxic chemicals in most room sprays. I have been using this for years. One spray freshens the room.

Nice product
Scent: Lavender
I love this light fragrance that’s not overwhelming and doesn’t leave any kind of sticky residue or film. I buy often.

Great for sensitive skin, cleans well.
Scent: Unscented, Size: 4 Ounce (Pack of 2)
Only soap I can use at the moment. I have extremely sensitive skin: I cannot do really any coconut derivatives or even palm oils but this soap does not bother me at all. I feel clean with no heavy scents afterwards (I use the unscented version) which is a win in my book. I don’t use it on my face or hair just as a body soap and it doesn’t make my skin feel prickly or give me any unexpected rashes/reactions. It is a little drying for eczema prone skin so I just use more lotion when necessary. You get two very large bars that last well for the price it seems reasonable, but honestly I’d pay anything to not itch at this point.

You will not regret buying!!
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I don't normally write product reviews but this soap truly deserves it. I had heard about beef tallow products as a carnivore dieter but hadn't paid too much attention to them until I found a huge mass on my thyroid. Suddenly, I'm looking at all the products that I use and am shocked that everything has endocrine disrupters like dyes and fragrances. This was the most natural soap I could find and what a huge turn around in my skin. I have always had certain areas that are habitually dry and even lotion would not 100% fix them. After using this soap for over 2 weeks, my skin is so smooth and almost has that glow you see in lotion commercials. I have not applied any lotion at all in the last 2 weeks and I'm softer than I have ever been. I even shaved with it and it was the smoothest shave I have ever had. I used to use conditioner to shave with and this soap is far superior. It is also far superior to the facial lotion soap I was using. My face isn't dry anymore and no more rebound oil. The people that I have told about this are immediately grossed out and think that the soap smells. There is an ever so slight hint of tallow but it does not last and once you start using the bar it isn't noticeable unless you sniff the bar itself. It does initially leave that sticky feeling that you get from Castille soap, which is strange when you're used to conventional beauty bars or body washes. But please don't quit using it! That sticky feeling is adding moisture and protection to your skin and once you towel off I promise you will not feel sticky. After a few weeks, I promise it won't feel weird anymore and you'll have the best skin of your life!! I'm sorry for the long review, but I am so grateful for this product. It is not only a beauty miracle but better for your whole body, no more toxic chemicals leaching through you skin.
And people are not lying when they say this soap lasts. I use it twice a day and I still have a good sized bar left. Also, it really does not disintegrate like regular bar soaps. A few reviews mentioned it being expensive and my husband also commented on this when I bought it, but in my opinion it is extremely cost effective!! This is my rationale, it replaces the facial lotion wash, shaving conditioner, and the need for body lotion and it lasts a long time. My other reasoning is that the long term medical costs of using toxic products just doesn't seem worth it.

Cleared up my skin!
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I have been using this soap for a little over a year. I was on accutane to cure really stubborn acne and when I got off my acne came back. I started using this paired with a beef tallow and honey moisturizer as my only skincare and it cleared up my skin so well. I love this soap and it is so natural and nontoxic. Amazing product.
