I'm going into my second year with it. So far, it has been great. There was a software update that needed to be done last summer to correct a glitch. After the install of the update, the unit is back to norm. The screen size is great, the fishfinder is top notch. User interface is easy. I recommend it and would buy it again. Only thing I need to adjust is the transducer; it will kick up at higher speeds...just need to tighten it up a bit. It has all the features of the E & C series (less the ability to add radar...it would take a second display) from what I understand. I have this on my 20CC SeaCraft.
