This unit is a couple of months old, I bought it when my 705 went on the fritz. But I decided that I like the flexibility of the 705 so I got it replaced on the re-furb program, no point in keeping this.
No marks, no scratches. Actually works very well at doing what it does.
It is the standard model, as described here ...
That means no HRM strap but does have the Ant+ stick and all the other goodies.
$150 plus postage.
