VIVOSUNHydroponics CO2 Regulator Emitter System with Solenoid Valve Flowmeter for Grow Room Grow Tent Garden House Aquarium

It’s probably my fault for not reading the listing properly but why would you sell a 110v American plug product in UK? literally the wrong voltage and connection type. If I got a converter it still wouldn’t work due to frequency 50/60hz. Waste of bloody time!

We've bought multiple Vivosun products including the dreaded house-burner oscillating fans. The fans were the only thing that Vivosun has made that are garbage. I was hesitant to purchase this product however, given the price and Vivosun's great customer service I figured I would try it out. So far it's worked perfectly at half the cost of the more well-known manufacturers. The solenoid that opens and closes the valve sounds pretty intense. It snaps quite loudly compared to the other regulator we have but it's still working great for us.

Phat farm -- where the buds are fat, and fat buds are phat.@CashCropCanada on IG - really upped tric production too.

This one is the exact same as the $90 Titan. I ordered a Titan CO2 regulator from a hydro shop thinking price=quality, only it started leaking, mostly just at the beginning of fresh tanks, but over 3 tanks it got worse and I couldn't get it to stop. I didn't have time for the run around and the warranty policy offered them any reason to refuse(if you turn the flow up past halfway warranty void). So I decided to 1)order a replacement, 2)tear into the Titan, see what I can see. Being Prime day, the Vivosun was only $32, as I ordered it I was thinking, man, that looks exactly the same as the $90 Titan. I fixed the Titan, better than new(or better than when I got it, it didn't seem new) and got this one today. See for yourself, one has a Titan sticker, one says Vivosun on the tank pressure gauge, other than that...identical. Oh, and this one was new. I would keep it as a spare, but I called Titan to ask a question and the tech warranty'd mine, but asked me not to ever work on them again, didn't even want it back, told me to cut the cord. I mean, cool, but what was I supposed to do in the meantime, that one won't be here for a couple weeks and I've got hungry plants. Get yourself some Teflon tape and seal up every joint you can, your tank will last longer.

Actuator very loud, constant buzzing. Flow ball doesn’t work.

Works good. My second buy of this item. The 1st unit lasted an extended season then failed.
