Bought it for my dad. Elderly people often have joint issues in winter, they’ve always used the Zhoulin spectrum device, customer service answered my questions very warmly and accurately. Delivery was super fast, received the machine the next day after ordering.

Urządzenie jest fajne, mama mówi, że ogrzewanie jest wygodne.

Simple and convenient to operate, adjustable heat, one-button start, convenient, easy to use, doesn’t take up space, a very good product.

이미 3번째 사용 중이에요. 처음 두 개는 301 모델이었고, 사용 효과가 매우 좋아서 여러 적응증에 대한 치료 효과가 좋았어요. 이번에 311 판형을 구매했는데, 디자인과 공정이 많이 발전했네요. 사용 효과를 기대해요.

I used one for over 20 years before, this time I bought a new model, it doesn’t burn anymore, the plastic design looks better than the old metal one. Very comfortable, chronic illnesses need slow treatment, this spectrum therapy device is good, I’ll recommend it to everyone.
