Warning!!!, do dot buy anything from Omega 2000 group. George the owner is a
lying cheat. I bought a OME 514. this thing is junk!! It does not maintain
temperature automatically, is has mechanical knobs!!(I learned this the hard
way) He said he would give me my money back, he gave me a return number, I
sent him the item and then refused to pay me. Stay far far away!!!
