I think this means that I can't walk away with it running unless I know
that I can get back within 3-4 hours because it will probalby clog in
that amount of time. That might not be a problem for most folks.

Well, isn't the thermal cutout really to prevent risk of shock or fire
from overheating, as opposed to preventing excessive bearing wear?
I would prefer a moter that can withstand the load of a totally blocked
media -- that design feature would be a better guaranty to me.

Absolutely so. But I'd rather not have to buy a timer to go with the
filter or, instead, make sure that I get back to it in 4 hours so that
I don't void the warranty or damage the thing. Actually, I want to set
it up, go to bed, and let it run overnight. OR set it when I go to

Because you get very little pass of diatoms while the media holder is
loading up, you can do this with very little fuss -- just turn it off,
wait a few secs for the gunk to drop, then turn it back on -- that
feature is very convenient.

Well, actually, it's not totally difficult to get a little bit passing
by the media holder while it is loading up. This happens if the media
holder doesn't seat just right on the nipple -- so technically, it is
not being used properly. The hole in the media holder, where it fits
on the nipple can become enlarged with use -- this is a situation that
calls for a few winds of duct tape to enlarge the diameter of the
nipple. But very little leaks in these situations, anyway.
IMO, the basic design is a great advance over the basic canister style
of the Vortex. I just wish it had a tougher motor and quieter bearings
-- in fact I suspect that many that come off the line have quieter
bearings and I happen to have some that should have been caught in
Quality Control -- IMO.
I could live with that situation too, if I could get the company to
respond to emails with more than a wink and a feint.
