As far as we know, the principle of most of competition around with 20 € bracelets is different from EmeTerm, which is based on artificial press but not TENS, such as Sea Band. They do not output any electrical signal. Actually, they are spot massage devices. EmeTerm is more effective and convenient than massage devices which are cheaper because EmeTerm can provide continuous stimulation automatically to the central nerve in order to prevent nausea and vomiting. We distinguish ourselves from these competitors with several key advantages, including a more effective conduction method, more skin friendly material, and a more convenient recharge procedure. Please see the attached document for a more detailed breakdown of our competitive advantages over other products.
