I have a Longacre 60 psi digital tire gauge I bought from Summit Racing in January 2019. I was having issues with a wandering zero point.
Here's a link to my loooong thread asking what folks preferred and issues with the above gauge (starting with post #35):

To get quickly to the point, over the last week or so I emailed them a few more times about what has been happening with it and gave them feedback about how I am trying to make it function correctly.
Yesterday, even though it is 3 years out of warranty, Longacre emailed that they're sending me a new 52-53000 DIGITAL TPG 0-60 gauge.
That certainly renews my confidence in Longacre. I will have no qualms about buying from them again.
