Riptide delivered! I made 2 2 minute comparison videos.
I turned off my return pump for the comparison.
My regular pump set up has 4 front facing power heads that I think are 540 gph each and one has a spinner. Then I have 2 mp 40s set at 70 pct on each end of the tank.

The riptide is set to continuous mode at 40 pct power.

My take. Noise is a low hum. Above 40 pct it gets louder and higher pitched, but in comparison to an mp40 its quiet. There are 4 modes. Continuous, pulse (you can set the time between pulses), alternating which reverses the flow at set intervals and finally feed mode.
I thought I was going to like alternating because the low flow spot for me is right under the unitn(look that the yellow plate coral and bubble coral in the bids). Reverse would have cured that as well as given some variation in flow. Problem is in reverse its too strong directly below the unit. It might be great for other set ups, but not mine. I'm going with pulse and I think I'm going to keep 2 of the 4 front facing power heads on. This will solve my one dead spot issue, give me some variable flow and I need some flow in that back chamber to prevent stagnation back there.
They supply you with a spare set of rotors and cages. This leads me to believe that they know the life expectancy of these rotors is relatively low and something that may need to be replaced every 6 months to a year.
Overall very, very satisfied and would certainly suggest buying one if you have a lot of pumps in your tank and want to lean out the look and save some electricity.
