I bought a bio diesel processor machine from Mr. Paul Davis sweet home biofuel. It ended up having a lot of problems. It broke down on me about 4 times I was able to make about 120 gallons from the machine. I ended up sending the machine back to Paul Davis and wanting a refund, I have not received my refund as yet and it has been at least 3 months since the machine has been in his possession I have emailed him several times and he has responded back saying he will be making the refund, that has gone on for several months he has promised to make the refund he has lied to me to many times this is why I am making this complaint. read full review »
