Shame, you already bought; Zandor and I both build our own cloners, If you're interested mine is located at...hydroponics forum...clones in 10 days/homemade bubbler...mine took 30 minutes to build...
I saw in a thread the other day a guy bought a bubbler on ebay, and it was a joke...
Now most of the bubblers and cloners on ebay are right-on, but this one was a joke...
Goodluck and I hope you bought the right one
