I've been looking at wave makers and somebody said look at Jebao. Can anybody tell me what the Characters stand for in front of the letters. I see PP RW etc. I am thinking of getting a pair of RW-4's or PP-4s for my reefer 130max. I cant find anything to say the difference. Are they worth a hoot? I know you get what you pay for and all but the MP-10QD are are over $200.00. Are they worth that much more?
