### ⭐⭐⭐⭐⭐ Great find
*by V***A on February 15, 2026*

Awesome gels, first time trying this particular type. The whitening effect is very visible even after the first wear, but most importantly there is no sensitivity even after using this gel 3 days in a row. Fantastic!

### ⭐⭐⭐⭐⭐ Does not make my teeth sensitive
*by C***8 on August 30, 2025*

Works well and does not make my teeth sensitive.

### ⭐⭐⭐⭐⭐ Effective Product
*by M***Y on January 2, 2025*

Whitens really well - much better than strips. You do need to get trays; I had some custom made at the dentist and use the product about once every three weeks to maintain my desired level of whiteness.
