She says give it a 4 as she has nothing to compare it against.  She wanted it to put on directly out of the shower to try to stay a bit warmer (thermostat keeps the house cooler than it is in the warmer months) instead of standing around toweling off.  It seems to be absorbent to the extent that she will often wear it around the house for a while after.  It appears to be comparable to the robes I see in some of the more upscale hotels which provide a robe for their guests (which you can often buy in their on-site store or web site for considerably more than what we paid for this one).  Just be sure to clean out the dryer lint trap after washing and drying it - before drying another load - the first couple of times but that's expected just like a new set of towels.
