Splitit helps consumers use their existing credit card to turn purchases into smaller, monthly payments.
The full amount of your purchase is authorized (held) on your credit card to guarantee future payments so you need to have at least that amount in available credit on your card.
The authorization amount reduces with each monthly payment you make until the balance is cleared and we renew these authorizations periodically. The previous authorization is removed as soon as we receive a new one.For more info, Contact Splitit Support

Reviews and Questions
- GBGina B.Verified BuyerI recommend this productRated 5 out of 5 stars9 months agoBulb & Bodacious
I've had my Sauna Space for about 2 years now and love it and use it every day. The bulb lasted a long time and I replaced it for the first time recently. Came quickly, beautifully packed and super easy to install. I'm so happy I bought this product and would like one day to make the investment in a larger system. I've recommended it to others. Feels so good! Thank you for this really nice company that makes lovely products.

Love this light bulb, especially in the winter. I use it daily. It’s been helping my skin and my mood! The red light and heat is calming and therapeutic, my dog loves it too!
- ANAdam N.Verified BuyerI recommend this productRated 5 out of 5 stars1 year agoAdded proton w ThermaLight bulb
Added proton w ThermaLight bulb to my Faraday set for some extra juice and it didn’t disappoint! Can definitely feel the difference with the new Thermalight bulbs vs the old school ones. Definitely intend to gradually replace older bulbs with the newer ThermaLight ones.
- AAAbdulrahman A.Verified BuyerI recommend this productRated 4 out of 5 stars1 year agoNice experience
Here I sit an hour a day before bed, and you get a very deep sleep, and more muscle relaxation, but you need a closed and small place to sweat, avoid lighting on the head, you may get a headache

I like to put methylene blue on my skin and shine near infrared love lights on me. You get energy through the roof. You need healthy energy levels in order to sleep well. Ray Peat. Tom Cowan. Giorgi Dinkov.
