I researched for months before choosing Pet Tracer. It was a good decision. Pet Tracer has identified precisely where our cat was every time we’ve needed it to. It’s fairly easy to set up (although the website isn’t always clear) the app is simple to use. I’ve never had to use the RF tracker so can’t comment on that, but the WiFi tracker has always been bang on. We almost lost our cat just before we got Pet Tracer so having that peace of mind is worth the higher cost relative to other trackers. I could do without the monthly subscription but that’s a decision for next year
