I bought two 28mm Gen 2. Such a dissapointment to have one read 0 bar. Seem from your FAQ that you are aware of the issue. Then why dont you test them before sending anywhere? It is all fine and dandy that you will replace, but there is still return shipping cost and all the other incoivinince and time wasted.
Proper quality control would solve all of this. But that is not something you company obvious cares about. Otherwise there wont be so many post with the same exact problem, meaning is it quite common.
I am brand new customer and already dissapointed with your company. Just a quick search in this forum and I am far from the only one.
PS: I think it is very greedy that you would have customer pay extra money for a seperate cable for updating firmware. I have never seen anything like that before in my life. You make new firmwares to fix bugs that you have left in your software. So why then would you charge customers to be able to get it fixed with a custom USB cable which BTW is not available in most of your EU vendors also no warning about ordering it. So have to pay extra 15usd to get if from you directly from US, plus shipping of course and then the customs duty. How can you consider yourself customer centric with something like this. The two guages that I bought 2 days ago have firmware from 2023 on them. Just poor, very poor.
Here are 3 pages of a customer who you seriously maltreated and you would not even comment in the thread. I wish I had searched here before buying anything from your brand.
