Several years ago, when I was still diving and actively considering going down the RB route, Revo seemed to be flavour of the day. No one has mentioned them in this thread, are they out of favour now?

The choice was a no-brainer over the other Inspiration-style units. Owning and diving a Revo has just reinforced my choice.
The Revo comes with an accurate and working scrubber monitoring system that tells you the remaining time on the one scrubber — adjusted for gender and weight — and will tell you if you’ve started consuming the second scrubber. The model is accurate and because the second scrubber is monitored it knows if you need to replace both.
So 1.3kg for many hours -- 3+ in cold water. Or two dives on Monday totalling 90+ mins in a freezing cold quarry (with the monitoring system estimating 2h45 left) and 70 mins in the sea the next day with it still estimating 1h55 for the one scrubber or 2h40 for both.
Next, cells. If you’ve only got three how can you tell that TWO haven’t failed or are reading unusually? In this time of acute O2 sensor shortages, aren’t you risking your life on dodgy cells? Having five, three on the controller and two completely independent cells on your independent redundant backup means you can validate your cells in the water and you can move suspected cells to the naughty step on the backup later. Actually had this happen last week where some moisture on a cell coupled with a slow cell meant the controller voted off the working cell. It all warmed up after a while so no problems nor worries.
And trim. I see seahorses with sticky up bailouts. OK it’s a personal thing, but I’ve heard that not all units like being dived flat.
More (possibly conflicting) information is a recipe for disaster imo. With cell issues it's the human factors cock up thats the problem.
With three cells it's abundantly clear if you have an issue. Even the much talked about double current limited scenario. It's also possible to diagnose the issue with three cells.
I could run my unit with 4 cells but it wouldn't provide any benefit over 3. Much like with 5.
How does the stack monitoring system work Wibs?
