I use the HydroPulse.  I lean over the sink but I'm still standing right
side up.

I use WaterPik, stand up and bend at a 90% angle between my hips and upper
body over the sink. Or like so:

My method:   I use a water pik with the Grossan adapter. ...I have the
flow a little stronger than the Dr. suggests, but then I don't have any
major blockage problems.   ...I bend over the sink with the device in
one nostril. ...I swallow, periodically, which permits a greater
retension of the liquid, then I exhale lightly through my nose.   ...I
do this a number of times, then switch nostrils. Then I go back, and
after the flow seems clear, I suck as much of the water in my nose as I
can, then spit out through my mouth.  ...I repeat on the other nostril.
(I irrigate about twice a day. ...I cut it out completely for a while,
but I noticed my sinuses gradually reverted back to being as they were
before)

If I have a flare-up, as I did a few weeks ago, I step up the irrigation
to 5 times a day. ...Once again, I managed to get through this latest
flare-up without having to resort to antibiotics.

If I develop head-aches from my frontals being inflamed, I'll switch
from using luke-warm irrgation water to the water being as cold as the
tap can provide.    ...Jon

I use a Hydropulse twice daily, standing with head perpendicular bent over
the sink.

Instead of 4-5 major sinus episodes a year, I now have 2-3 minor sinus
episodes a year.

my thanks to Dr Grossan !              AW

I use hot tap water with Kosher salt in palm of hand with head down
over sink as much as possible. Works great.

Plastic bottle.

I've used the Nielmed bottle for years. About two weeks ago I started
using Hydropulse. Decided I would give it a try. At this time it seems
like it may work better. It defiantly seems to get the saline into the
sinuses better.
