Overall a high quality product and with decent instructions besides some poor translation/grammar. The biggest challenge I had is I initially only did 3/4 wraps of Teflon tape like I have in the past without any issues. I made sure to not over tighten and then planned to turn quarter turns until no leaks. I got all four npt fittings way tighter than I was comfortable with and they still leaked (very fine drops). So I had to take all of them out and inspected the thread. At first I thought I saw cracks, but then I noticed that there were multiple (four to be exact) lines in each thread evenly spaced apart. I think this is from the industrial pipe thread tapper at the factory. Regardless, these lines are prone to leak if you dont get sufficient Teflon tape. So I did a solid eight turns on every fitting and gave it a go. Again, made sure to go just past tight, turned on the water and watched. The very fine drops formed and I did quarter turns and waited to see if leaked. Eventually got all four fittings not cry tight, but not leaking either. As long as they dont start leaking again, I will leave up the four stars.
May need to use more Teflon tape than usual
