Review on PerfectPrime Professional Manometer Differential ±83 02InH2O by Tony Suggs

I bought a Perfect Point AR168 3-11-21 from Revain and it arrived on the 3-13-21. I couldn't get the device to work at all and when I opened the box there were two noticeable scratches on the screen. I rated it one star. I sent the first unit back and they sent the second one 2 days later. My first use will be in April to measure the pressure around the car during the race but it seems to be working well. The second device has no flaws, but it also didn't have a battery (I don't care) as stated in the description. I appreciate the speed with which Perfect Prime/Revain sent a replacement and wanted to revise my review.
