Good starter AMS if you're looking for the basics.
I work for an association management company who currently has 5 accounts with Wild Apricot. We've been customers with them for almost ten years. To be honest, the only reason we stayed customers (apart from cost, which is at the lower end of the scale) is because I'm an applications engineer and I was able to create a multitude of workarounds to make Wild Apricot more robust. Another issue I've noticed is that when they make fundamental changes to the software, they don't poll their customers to see if it would be a good change or not, and they don't build in a kill switch when they create new features or changes that might affect some of their customers negatively. This is really the reason why we're in the market for a new AMS - their recent policies have been disasterous for us.
All-in-all, Wild Apricot is a solid, reliable, basic system suitable for small associations and groups that don't need all of the bells and whistles.
