So when did floor mats turn into this whole thing where we're comparing receipts and feeling dumb about a purchase? I mean, a mat's job is to sit there and take abuse, and if a $12 slab of rubber does that better than the $90 one, then the $90 one just had bad design, not a bad price. The real problem is that curled edge catching your shoe, which is a safety thing and would bug anybody. But maybe it's just me, does it really matter either way as long as your carpet stays dry? Feels like you got lucky with the cheap ones and unlucky with the fancy ones, and that's about all there is to it.

Wait, was the comms failure really from the pinch, or did the umbilical actually get cut? Because a pinched hose usually kills your air, not your comms, unless the wires run inside the same hose as your breathing gas. On most of the gear I've run, the comms line is separate, so a sharp edge on the guide frame would have to bite deep enough to nick the wire before you'd lose the tender. If you lost both air flow and comms at the same time, then yeah, that edge cut through everything and you were lucky to have enough gas left to make it up. Either way the split sleeve and tape is a solid cheap fix, but you should also check the hose after every drop for flat spots, since a pinch can damage the inner liner without showing on the outside.
