DELTA Pro's Smart Extra Battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro.

This balm is Magical!
Scent: Vanilla, Size: 2 Fl Oz (Pack of 1)
This product was a life saver! After using the same face moisturizer for years, I suddenly became allergic to it. Overnight my face became swollen, red, sores that oozed, it was disgusting, embarrassing, and painful. I was diagnosed and treated for impetigo- which I knew was not the cause. But I didn’t know the cause until it cleared up and I went back to the old moisturizer because I was sure it couldn’t be that after years of use. But it was and I had another outbreak. So I researched an American made product and found this balm. It is magic! Within a week of using it the symptoms were gone! I love the scent, the protection it provides, and just how very soothing it is on my face. It is the right thickness to keep my face from dryness all day long. I love the feel of adding a glow to my skin with a rich oil that is pure and allergy free. I’m on my second jar and will be a loyal customer from here on out!

Best on the Market
Scent: Citrus, Size: 2 Fl Oz (Pack of 1)
Been using this product for about 8 months, its all i use. As soon as I get out of the shower, I use it. Then at bed time.
I use nothing else. I wish I knew about this Beef tallow sooner. I am 60, and will continue to use this. My face has never been softer. and My wrinkles are definitely not as prominent.
Great product!!!! Great Price!!!!!
Just but it and try it. You you know instantly. Your face will feel so soft, and moisturized . And its Not Greasy.

Great Skin Conditioner
Scent: Unscented, Size: 2 Fl Oz (Pack of 1)
I ordered the unscented, and it is truly unscented. It is solid, but by rubbing you finger around the top of the tallow, it immediately begins softening and melting. I used too much the first time, as it leaves a sticky/tacky film on the skin, so as the instructions say, a little goes a long way. Even though the next time I was careful to use very little, I do think it leaves a little tacky and greasy feeling, but it does soften and protect the skin. My only complaint is that due to the size of the jar, and if you have long fingernails, you can't just rub your finger on top of the tallow without getting it all under your fingernails. I'd like the jar to be changed to a short wide mouth vessel, hence only a 4 star rating.

Excellent ingredients and product!!
Scent: Unscented, Size: 4 Fl Oz (Pack of 1)
I rarely do reviews, but I am extremely impressed with this product and company. First it comes in beautiful packaging, the ingredients are pure, great, and so healthy! The price is good, and there isn’t any rancid smell which has been an issues with other similar products I’ve bought. I specifically bought the unscented to make sure it didn’t smell rancid, and it doesn’t. If I had one criticism it’s that there isn’t a phone number for contact just the website. I’m elderly, so I prefer to talk with someone. But, after I just experienced 2 bad experiences with similar products that I had to return, I so happy that I ordered this one. And, I’m so impressed that I’m going to order more now! 😁 Thanks 🙏 Terra Lotus for providing us with a great 👍 product!!

Worked well with us!
Scent: Citrus, Size: 2 Fl Oz (Pack of 1)
I’ve been trying different products for my daughter’s eczema-prone skin. Her skin was getting really dry, irritated, and rough in certain spots, and this balm has been super moisturizing and soothing. I love that it’s made with simple, natural ingredients and doesn’t feel harsh on her sensitive skin. A little goes a long way, and we’ve noticed her skin staying softer and less irritated after using it consistently. Definitely one of the better products we’ve tried lately 💛
