I have been using this product for many years and have found it to be generally fast and dependable. However, I must mention that the lenses can be quite expensive for what they offer in terms of quality. Additionally, the company tends to promote certain alternatives that may not be suitable for everyone, such as ACUVUE compared to CRYSTAL. The CRYSTAL lenses are only suitable for a maximum of six hours of wear, while the ACUVUE lenses, despite being two to three times more expensive, can last for at least 24 hours (although it is not advisable and 18 hours is recommended). I would suggest that the company focuses on providing more value for the cost and prioritize quality.
