You could drown someone with this, and they'd thank you because it feels so good.  I won't admit I took out the flow restricter, but I took out the flow restrictor and am thinking about putting it back in.  I like long showers and before this I could not run my 80 gallon water heater out of hot water taking a shower.  With the flow restrictor out and my other shower head going, I can run it out, so either I need to run one or the other, shorten my showers, or put the restrictor in and see how well it works with 2.5 gallons a minute.  It isn't as classy looking as many of the shower heads I've looked at or owned, but damn.... it feels good.  Excellent coverage and just drenches you like a warm monsoon storm.
