The Trinity bag is a cheaper copy (like a lot of their stuff) of the real Magic F8 bag. I have the F8 bag and it has plastic boxes that I've never had a problem with no mater how much weight I've had in it. Also, I only spent $145 on my Magic bag. That link for the Venom one shows it's only $15 cheaper. The plastic boxes make all the difference and make the more expensive one worth it. I've had mine for 2 years and don't plan on needing anything else for a long time. The one and only problem I have is that in order to keep everything organized, it has to stand up. It can't be laid down. Otherwise all your tools and everything will spill around. And being the neat freak I am that just can't be.
So it can't fit in the trunk of a car. It has to stand up in the back seat. Small price to pay to me.
