Can you post some links? Every time someone talks about a G2 it's usually always a G1 V3. I've only seen a couple actual G2's and those were non common leaks (like shipping damage etc). It's also pretty suspect a local builder would be repairing them if they're still under warranty. The G2 has only been out for just over 2 years now.
Red Sea definitely has issues with the G1 which is costing them a lot of money with all the replacements they have to hand out, but let's not talk about G2s in the same light from mere hear say. Yes, Red Sea deserves a bad rap, but let's at least be accurate with the bad reputation they deserve.
