The product we purchased was battery operated. It turned out the battery portion did not work. Furthermore, the item had fit issues and was not clear from the description of this potential issue. Nevertheless, the customer service was stellar in response time and appropriate response. A complete refund was given to the original credit card and not just a store credit, due to the issues noted. Very reputable service, although some descriptions could be improved (Reason for 4 stars due to description unclearnesd but customer service is very good.)
Fyi, there is a cannabis in the ingredients if that makes a difference for you. It just says natural ingredients or something like that. I'm sure the product itself is fine. We just don't use that, so wasted our money.
does not do anything as far as taste, or the temperature difference discribed
I have very sensitive skin, so I have been using Intimate Earth for years now, as I couldn't find other products that wouldn't cause itchiness or irritation. For me, this is a go-to besides the obvious reasons.
