I received the package couple days ago. Upon opening of the package, I noticed that the tire sensors were out of their designated location and spread throughout the box.
Using the device was really easy, however, one recommendation is to include a mounting device so that on some vehicles, it can be mounted so that it won't slide around during the drive.
The actual sensors look great, however after putting the anti theft device, I noticed that the battery compartment is easily removed if someone were to attempt to remove the sensors. The problem with that is: batteries are fairly expensive these days, so it will accomplish the thief's goal at stealing something.
The app itself is simple which is more effective these days. I brought a lot of negative feedback in this post, but I prefer to say all I can before the official release of the product. I will continue to monitor for errors in the product.
