“They are about 10-15 psi out from the measurement, more trouble than worth as each time using them have had to pump the tyres back up as they have deflated too far.”
“I am very impressed with the Boss Tyre Deflators. They are simple to use, speed up the deflation process, and were within 1 PSI of the target presssure on my first use.”
“Great little product. Speeds up the process for sure but need to get used to the actual psi as the gauge measurement are so small and hard to get right. I have only used them twice though”
