I was hesitant at first because it's a bit pricey but with so many positive reviews and when it comes to my Harley Davidson Street Glide I really just guessed my tire and hoped the pressure was close to what owner Manuel is asking for cheap inaccurate sensors with wild readings, which made me uncomfortable. I have TPMs on the bike but they seem to jump due to hot and cold temperatures but this bad boy gauge has put my mind at ease now I know my tire pressure is accurate every time I roll down the road you won't regret and it makes you feel safe
