Excellent product that offers 5 wave lengths. Half or better than half the cost if bought in the US. The cost is worth the wait, and it arrived 2 weeks earlier than expected. Thank you. I have purchased twice from this company and no disappointments.

I’ve purchased multiple red light units from Amilia He and have been happy with the service and quality of each one. She is very responsive and answers all my questions. I will keep buying from her in the future. Highly recommended!
