The product I bought was highly rates and was offered by Moonhara. What I received was a Chinese knock off. As this was a blood pressure monitor using an unknown model can be dangerous. Moonhara wont give you a full refund and wont pay for the return postage. Please look for alternatives to this Hong Kong based company.
Tip for consumers: Stay away from this site.
Products used: I ended up receiving a partial refund and then having to destroy the product.
