I ordered this sample with the view to adding it to our product protfolio. The build quality is good and it has some very good features and looks nice. Unfortunatly the product is registered incorrectly under the CE marking. The factory has this registed as a home massage device, in the EU and UK Tens machines are a MEDICAL DEVICE and have to be registered with the MHRA, and have to be registered correctly to sell within Europe. To sell this product as it is, is illegal. Which is such a shame as the product is good. If ypou decide to register the product correctly within Europe, it would sell very well.
