I use the Logger to collect location data while photographing and cycling. Both finished the instrument properly, without the need to adjust and configure much. Navigates I put the unit on. The Royaltek receives even then a signal when it is stowed in a bag, you have to him not so always carry around openly. Even a track on the plane, I can record the logger depended on the seat directly in front ;-) window. Something impractical the cover for the USB mini port is running, this affects not particularly stable and safe and could well suffer with frequent use. Also inconvenient is the much too dark status LEDs that you can barely see outside in the sunshine. The operating time with batteries could be a bit longer, but is still ok. For these shortcomings, I prefer from a star, otherwise the Royaltek is simple and practical and does what he should.
