Good quality
Good quality second stage regulator. Installed propane line to new generator and factory set @ 11 inches water column. Works fine from a known manufacturer.

Value for the money
Great secondary regulator, has held up well for 1.5 years. It is pretty large so make sure you aren't mounting it close to a wall where you won't be able to turn it down on the pipe. Was a value for the money.

Works great for pool heater or generator
I used 2 of these off of a 3/4" tee pipe. One to a Pentair 400k BTU pool heater and the other to a Westinghouse 8900 watt generator. The output to the generator had a 3/4" to 3/8" compression fitting adapter installed on the regulator output and then a 3/8" propane extension hose fabricated with female ends. The generator started right up and the Pentair heater likewise. No adjustments to either device were needed or to this regulator. Very happy.

Works good
Works good just wish it had everything to mount to the house and fittings for the gas lines but it did the job.

Good quality
I needed to send back as I needed a two stage regulator. That was what I thought I was ordering. It was a single stage and would work for what I needed. Read the description carefully. Refunded without any problems. I would highly recommend as it was very well build and appeared to be durable. Reasonable for the money

Excellent volume through this regulator.
Plumbed in perfectly. Cheaper than having the old one recalibrated.

Great item, make sure the vent is in the right orientation
Happy with the quality of the brand. Just make sure you order one with the right orientation for the vent. This model has the vent pointing toward the inlet. I needed one that the vent points toward the outlet (the gas line on my setup runs down into the ground from the tank). Had to return this one, but thankfully Emerson-Fisher makes this same version with the vent pointing down (toward the outlet) with model number R622-DFFXB.
