Seems to be a nice tool to have in your car. Just ordered one for myself. especially if ur car is at home most of time :o)
Few interesting points are
- High-tech solar power board supplies enough power, no need extra power!
- LED screen display , so works @night also
- Four units with PSI Kpa Bar kg/cm2 your choose
- A bright LED light special for night
- Digital readings up to 99.5 PSI
- A 2cm metal bar (extendable)is available for let out extra gas
- Pressure range: 2-150PSI
- Accuracy: +/-0.1 PSI
Save gas and extend tire life with correct pressure & Little investment, save much more money -- that's their ad :)
Also, it may be able to measure Tyre thread depth too.. !!
