Thats nice. the only draw back I see opposed to the home depot one is that you can't tell how much is in it without taking it off.
True, you can tap and install two 90? elbows top and bottom with a clear tube to indicate fullness.
It's pretty easy to just reach under and unscrew the bottle and check as well.
Mine has been on for just over a month now and has only a few drops in it. this was better than my Husky Moisture filter I used from the DIY cheap catch can thread on here before. With the OEM style PCV back in the car, the higher vacuum was allowing some of the oil residue through the smaller catch can.
