I got the discount code and ordered a replacement and indeed got 70% off, so we will see! The Customer Service lady I have been dealing with has been very responsive and asked me for a screen shot of my order number and she said she will work with the distribution center to ENSURE I get a new, non-returned item this time, so what the hell, going for it-
My return went to a Amazon facility in Pa, my new one is shipping out of Washington state so for sure it is a different unit!
Got the new one yesterday. Fresh and unopened. Registered it, updated it and used the borescope to peek in the cyl of the 500! Nice tool. I like that I can email the test reports, any camera pics or video's I take with it etc. to myself from the unit. Has a MicroSD slot as well. And I got it in the end for 275 bucks! Even has a built in browser since it is Android 11 based.
