Review: Easy install, and pitch perfect price works great - OK, so I bought a couple different varieties of these and this particular version by far is one of the most accurate ones at the price point that it’s given. Learning works beautiful. I have it set for every 12 hours so I get two updates a day. Instant check on my vehicle via the app click the button and I’m in. I have an Apple Watch so that works just as easily so I can check it. Find my Apple Watch. Easy install positive negative done. Very slim uses the newest Bluetooth 5.0 I believe is what’s advertised and I can access my car on my second floor of my house while my car is in the garage. Has a graph which works awesome. You can take the graph and export it out if you want to. That’s pretty cool you could check the Volkswagen. The car is cranking using the app. can also verify that it’s charging while cars is running. That’s pretty cool. So if you’re reading this take a chance it’s worth it.
Review: Works well for my Ford Fusion using App on iPhone 14 - I like the Bluetooth 5.0 extended range and reduced power consumption. It was easy to connect to the battery, download the app to my iPhone 14 pro, and connect via Bluetooth using the 0000 code. I placed the unit on the top of my battery using the provided 3M sticky. My 2012 Ford Fusion is outside in the driveway and I can connect with it from about 30 ft. away while sitting in the Kitchen. I received an alert this morning indicating that the battery was at 100% charge, which makes sense because I drove it late yesterday. I don't drive the car often and the battery drains slowly due to the factory security system/forgetting to remove the USB charger from the 12V outlet. After the battery went dead several times it was toast even though it was less than a year old. The attached pictures show my app settings, the alert I received reporting normal status, the app's voltage status graph, the app's cranking voltage graph, and the app's Trip log. I am still learning about the app. The true test will come next winter when it gets cold, e.g. will the sensor continue to work when it gets below 0 F?

### ⭐⭐⭐⭐ Short range so far.
*by N***N on September 28, 2025*

When it connects, nice. But on my car ten feet is to far. 4 stars for quality, but not operation. Maybe my cars hood to much metal ? Koni. UPDATE distance up to 20 feet now ? Better next day ? or weather effect.
