I use the Poseidon reg bag and love it! I fit my SM regs, hose clamps, hose retainers and bolt snaps in it plus my dive computer, extra bits and bobs and a few tools. It has held up very well.
I use it often here in Bali but mainly use it to hold the transfill whip so I can add a little more gas into to SM cylinders when doing three dives in a day. I bring the whip, tools, zip ties, o-rings and a few other items specific to my needs. It has taken a beating and I have had zero issues. Plus the zipper is nice and has never failed to work unlike some of the other brands on the market.
