ED M: I replaced some failed USA ( name brand high end regulators) that all failed the same day ( after about 20 years). Usually the seals or diaphragm embrittle with age. So this is way less expensive. I also saved a few bucks by getting this one - just the reg with no hoses. My old hoses are perfect and fit up to the brass adapters ( included). Brass threads and fit up all excellent (machining and casting).
Seems to work finely, the solid brass reg reaction to full cylinder pressure is stable and solid. The reg/flow adjust - full off to full on is smooth and regulates linearly along the full rage. The low Pressure (plastic) flow rate meter is dual incremented for Argon and CO2. So far so good. Let's see if they last :)
SOLID CONFIDENT PURCHASE

Ashley: 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!

laura: -There is a reason it is cheap. Leaked at almost every joint. Take all the fittings apart (which is very hard as it looks like some form of cheap Loctite sealant that just glues the fittings together) and replace with thread tape before you even try to use it. Don't allow any of the debris from the Loctite substance to get in any ports while disassembling/cleaning.
-Overall it seems like pretty decent quality, the flow gauge seems to work well down to around .5 schf where you may have to tap the tube to get the ball to lift.
-Solenoid is okay quality, not sure on cycle life though.
-Overall if you're a bit handy, these are great if you keep in mind the points above, but due to shortcomings (mainly the leaks), it's a 3 star for me.
