Solid GPS delivery was fast, and it was easy to set up. The features are great, perfect for monitoring my boat that is in a pen on the water at a yacht club. I turned on the Watchdog mode and that works well - it's good that it turns off after the first alert so I don't keep getting messages whilst using the boat myself. I'm not getting any false alerts with the slight movement of the boat on the water which was a concern of mine with other trackers.
