Pros: Fast delivery. Reasonable price
Cons: The instructions from the manufacturer are a bit vague and pictures don't exactly match reality
Arrived within two days and was exact manufacturer's spec replacement. Kit included a roll of Teflon tape which I didn't need but is necessary. On my filter the guage screws into an adapter that screws into the filter housing. That adapter has an O-ring that I might have lost without realizing it. It's mentioned in the instructions but not in the drawings.
