Unfortunately, the device is not convincing. It works when it is not just in the GPS area, only very inaccurately. For me, with 1.5 km deviation. In the field of more than 5 Satellite however up to 5 meters. That could convince. The website to display the GPS data is also very easy to knit. Neither high nor visually convincing. The sending of data is faster than other varmints that's good to evaluate. In the 3 days test phase I rarely had enough satellites for good reception. Thus, the product is unfortunately to be desired. Comparable devices are correspondingly cheaper. Size and appearance are visually good, but it decides not the quality of the product. It's too expensive for what it costs just 40.
