Only on minor annoyance is the adjustment for the number of bubbles is VERY finicky and sensitive. I bubble one every 2 to 3 seconds in my 15 gallon tall tank and adjusting it was an exercise in frustration as turning the knob was a matter of half a millilmeter one way v.s half a millimeter the other way.
Once set however, I've never had to adjust it again. It's a very reliable solenoid and valve.
Don't forget to put in a check valve to prevent water getting into the mechanism...
Negatives: Gauges have colors of rainbow, make reading of pressure difficult. Washer has uncommon size, may make replacement a choir.
No manual/instruction and info on warranty were provided in the box. There is no indicator light on solenoid showing when unit is on/off.
I will do an update on one of the most important factors; longevity. My AquaticLife regulator died after 16 month, disappointing. If this one still working after a number of years, I will upgrade my rating to 5 stars, despite the minor flaws I noted.
I set this up 3 days ago, no instructions but really none needed. So far seems very solid, goes off and on with the timer reliably. Once it is set to amount of bubbles per second that you want it is stable, no having to recalibrate. No bursts of Co2 when it comes on in the mornings. So far a high five!!
I will update this review after it has been up and running for a few months.
It has been a year almost and this is still going strong and reliably.
