So far I am very pleased. The one thing I don't care for is the manual. It is essentially worthless due to the way it is laid out. As Larry said, the availability of free software updates on-line is nice. They have greatly improved their user interface sine I bought the unit. I also really like the BR-24 broadband radar. Short range sensitivity and resolution are fantastic and I really like the instant on capability. If you plan on upgrading your radar, then you should consider an HDS unit. Mine is the HDS-5M without the depth sounder capability. It was under $600 when I bought it
