Bests & Worsts Reviews from Amazon

I dont usually review products because they rarely live up to their promise but this product is definitely as good as it claims. This product is well designed, simple to use and works flawlessly. How it works: So if you arent aware of how this things works here's a summary (some of this information is available on their website, and being an engineer some of it I just inferred myself). It comes with 2 peices a base station and a collar. The collar has a cellphone chip in it and a gps receiver. It can detect that it's near the base station and in this situation it wont activate the GPS (GPS burns battery power so this functionality is key to its excellent battery life). If the collar loses the connection with the base station (your pet is outside a preset Tagg zone) it will activate the gps and send a signal through the cell chip to Tagg and they will email or text message you with a low quality map indicating where your pet is. If you activate 'tracking' it will email/text you every 3 minutes with a new map. The emailed map is quite poor but you can also track your pet on an iphone or ipad. And because it uses a cell phone singal to transmit its coordinates there's no range limitations so your pet could run off to texas from washington and you could still track it. This service costs about $8/month for the first pet and $1 for each additional pet. That might seem a little expensive but most other products costs hundreds of dollars and require you recharge the battery daily and and are not nearly as simple to use and lack many of the features like notifications or alerts. Now the Tagg zone is an area you setup on their website to indicate where your dog is allowed to go without setting off the alerts (emails/texts). It's quite large and must be circular in shape (i would guess the radius is about 250 feet) so if you hoped to get an alert as soon as your dog ducked under the fence that's not going to happen. Now if your dog is within the Tagg Zone you normally can't locate it using the 'locate' feature, however there is a button on the base station that if pressed will ask the collar to transmit your pets GPS coordintes to Tagg and you will get a notification. My Experience: On a single charge the tracker lasted 3 weeks and this included my dog being outside the Tagg zone about 6 times for a combined total of about 2 hours. Each time he left i got a notification about 3 minutes after i noticed he was gone. I would grab my ipad and jump in the car and setup the 'start tracking' feature which would update his location on the ipad app map every 3 minutes. Most of the time i was able to find him within 1-2 more updates and every time he was exactly where it indicated. 3 minutes might seem like a long time and it is if your tracking a car downtown but for a dog that's just wandering up the street it's more than enough. When the trackers battery was low, Tagg emailed me and told me to recharge it on the base station, and when it was done charging it emailed me and told me to put it back on him. It's a bit bossy, but then again so is my wife. Pros: *long battery life even in tracking mode *very accurate *inexpensive *works anywhere you have cell phone reception *alerts for outside Tagg zone, low battery, etc. Cons: *tagg zone is quite large *emailed map is poor quality Notes: *only transmits coordinates when u try to locate it or in tracking mode *tracking mode only sends coordinates every 3 minutes
