My frustration with this stuff is that these companies come out with these cheesy products like "sharkbites" for refrigerant and line sets that are pre vacuumed etc etc and they are trying to make a buck by making hvac diy. We've been dealing with a diy minisplit install at work that has been a real PITA and frustrates me even more with diy products. Your testing is a totally legit thing to do. Again sorry about that, it's the products that frustrate me. I went back and read my first post and realized I worded it way too aggressively. Your concern about leaks is well founded but what's the harm with doing some tests on a new product and asking if anyone has tried it?I gotcha and I apologize.
