The ingredients are top-notch and I appreciate the herbal approach. However, I’ve used cheaper ichthammol ointments from the pharmacy that work just as well for half the price. It's a solid product, but definitely a luxury choice in this category.

The price is great, but the installation was kind of a pain because the cable was slightly shorter than the original. I made it work, but it was a tight fit. Mileage hasn't really improved as much as I hoped, but at least the error code is gone.

Sad to say this broke me out really bad after just two days... if you have super sensitive skin or are prone to cystic acne maybe skip this one because the silicone feel is very heavy.
