I have a 100g but have not set it up completely yet. I am doing custom plumbing and haven’t found the time to plumb it yet. I can say that they look really nice in person, the stand is nice from the standpoint that the side panels come off but feels a little light in person but I’m not worried about it enough to go with something else. I will say the one thing I’ve run into is that plumbing is all in metric so make sure you keep that in mind while plumbing. The sump seems pretty nice, glass and sturdy but bare bones (which is fine for me). If you live in the LA area, Tongs had a 100g on display in Fountain Valley. That being said I think it was an early one or something as mine looks nicer in all reality, theirs has some weirdness with the black back and had some stray silicon from what an employee told me. As far as customer service it so far seems meh, I have dealt mostly with tong which was amazing as he took care of anything I needed but when I called to ask a question to mode directly they didn’t seem super enthusiastic to help. I may have had a strange question (apparently they changed sumps for the 100g between when they started and supplied one to tongs and when they delivered mine) so that may have contributed to the confusion.
