Very well made. I had a constant problem with the TPMS sensor on my wife's minivan with my old sensor, but the alarm reset as soon as I went live with the Rhino sensor. The old one was far away. Spend 20 euros, it's worth it. Oddly enough, it doesn't say "Made in the USA" anywhere on the meter or on the box. That may seem like a lot of boasting to me and a little disappointing.
