That is crazy. I never had any issues with my Jebao DP4. I found that sometimes the issue is that the hose gets stuck together and that only happened once to me on all 4 heads when I first got it, but I took them apart, moved the tubes around and twisted them and viola. No issues in over 2 years.
I am slowly getting back into the hobby and I plan to use the same Jebao. Mainly because I don't have room for 4 more outlets, but if you do, good for you and definitely go with the BRS ones, I have read great things about them.
