The Naturals line and the personal lube what I can attest to and are the BEST I have seen in my 20+ years of nursing.No sticky residue or taste. Non-staining. Easy to use. Easy clean up.Been using this brand for two years now and I have recommended it to every friend and patient because of its ingredients and effectiveness. Especially for cancer patients who have so little control over the side effects that are ever lasting. Even seen this brand carried by stores that cater to people undergoing cancer treatment.I will caution you from purchasing this product from any other site. Twice did I receive a product with a lose safety seal, so I firmly believe it needs to be purchased directly from the manufacturers site. If there is any issue with a product, they remedy the issue without hesitation or hassle.Highly recommend!
