Really depends IMHO, at least when it comes to the APs. Yes, it's not enterprise-grade, but their APs are also way cheaper than anything enterprise and do the basics well enough. Average small business office use doesn't require much in the way of features, although how long various RADIUS features took was a bit embarrassing (I seem to remember putting clients in different, RADIUS-controlled VLANs wasn't possible for a long time).

Never really trusted their other product lines.
