I have bought 15 gps in total over the last 4 yearssome of them have been a bit of a hassle BUT have received a super good service from them every time because they always respond to my emails and if there are problems with the gps, they have always fixed it quickly and I can really recommend them.

I got my cargo bike back

I got my Bullitt cargo bike back. Last Monday my bike was stolen in front of the office. There was a tracker hidden under the bike. A little later in the evening, the tracker reported where it was. In the shopping centre. I went there, found my bike after 5 minutes and it was back after 5 hours from when it was stolen. After 5-7 stolen bikes, it was a new experience to get your bike back.

* RTC = Real Time Clock. The product knows the time and is able to send positions on specific time/day instructions as opposed to sending by predetermined cycles. While Cobblestone is able to send on a predetermined cycle, e.g., 'once every ~24 hours, approximate time', Gemstone is able to send on a given specific time, e.g., 'Tuesdays at 5:43 AM and Fridays at 3:40 PM'.

**OTA = Over The Air, wireless. This allows for future firmware and feature upgrades of the products even if the product is in the field."
