Be aware of customs charges
Slow delivery. The device itself works fine, but a month later I received a letter demanding payment of customs duties — about 30% of the device’s price. Although the website appears to be based in the EU and advertises free delivery, the product is actually shipped from Hong Kong, and the buyer has to pay for import. As a result, the final price is far from what was expected. Also, the website disables the option to leave a review once the device has been purchased.
