Great value
I purchased this for my co2 kit that is another brand. That solenoid kept failing after multiple replacements. Now this has been working for months now with no issues except occasional bubble bleed for about an hour after shutoff and I will not the plug where the power supply connects seems a bit fragile. That being said I highly recommend. You cannot deal it at this price.

Works exactly as it should!
I’ve seen very mixed reviews about this product, I’ve had it for about a month now, and it works great! It’s not fragile like others have said, it was easy to set up, overall very happy with the product, I hooked it up to a timer so while I’m working it will come on! Very happy!

DO NOT BUY
I would give this zero stars if I could. The solenoid is INCREDIBLY fragile, and while I was doing my first change, my hand slightly bumped up against it and parts fell everywhere, and were incredibly hard to find and put back together (especially the staple looking thing). This is the only review I have ever written simply because I felt I had to go out of my way to warn others about how terrible and ineffective this product is, clearly dropshipped as well which I don't usually mind if there is decent QC. I cannot stress this enough, please spend your hard earned money elsewhere.

Cool to the touch, works, good instructions
I bought this to replace an FZONE solenoid that ran too hot for my desktop CO2 system. This Clscea solenoid is warm to the touch when running, but does not heat up my bubble counter or regulator as the FZONE one did. I like that the instructions include maintenance how-to. I am using it with pressurized CO2, the hygger system with 45g canisters. I don't know how it will perform with yeast CO2 or reactors (humidity).

Disappointed
I can't believe that this item stopped working. I bought this one in January and today I realized this one can't shut off my CO2. Moreover, I'm not able to return this one or get a replacement one because the return day is over. So so sad 😞

Works better than the one that came with my CO2 reactor kit!
This is wonderful every single thing about this is an upgrade from the one that came with my CO2 reactor kit, which was not cheap. My power wire came off on the original solenoid, I got it back on but I should never have had the issue. Also it started leaking water I had to use plumb tape on the original. Now with this upgrade I have 0 issues the built quality is better, how the power connects to it is better, no more leaking. I couldn't say anything bad about this because it's literally better than the one that came with my kit, WONDERFUL!!!

It worked fine for a month until I added a co2 metal check valve after switching co2 diffusers that didn’t have a built in check/return valve. Be cautious of this! Had to return it and get a new one. Will try to use a regular o2 check valve and see how it holds up - would love to try other options but there’s only so much double headed mini solenoids available in Amazon. Will update later to see how it holds up Also my co2 system is a tropica 95g attached to a soda stream.
