i purchased a lowrance gimbal knob for hds 5,7,8,and 10 from amazon. when i received the product it was not like the one i had, so i called dfna to see if maybe it was the wrong one that they sent me. the individual on the phone (charles i think)started off with a bit of a attitude saying that the product is pictured on the site. i stated that's fine but it was not like the one (original) i have. he then his more attitude and tells me that he is a offshore fishermen and these knobs are the best and were pictured on the site. i asked him why was he having an attitude with me the purchaser of his product and again more attitude;so i gave him my attitude and some not so choice words.this is when he hung up. my only reason for calling was to find out if it was a mistake with sending the wrong product and to possibly get the right one. i will make it my life's goal to make sure that people i know, meet or interact with know not to purchase any product from this business. hopefully he will get the point and learn to do a better job with individuals that buy products from them. read more
