Hi,
Yes it is the same one that I got off ebay from Hong Kong. I have had it for 4 months and it has done the job very well.
I have used it with a glass diffuser that I also bought from HK, all worked well but I traded up for an atomiser from Aquaessentials (not because of the regulator). However, I just could not get a constant steady flow, ie the bubble count fluctuated over a 10 second period (fast - slow) Aquessentials said was due to a faulty regulator..... I immediatly bought a JBL reactor and have been using that for a couple of months and everything has been great.
