I've used their GL-AR300M model for a few years quite happily. Very flexible, i.e. wifi interface and two wired interfaces, and can mix and match roles however you like (e.g. wired uplink & downlink, wifi up/wired down, wired up/wifi down etc), combined with the ability to terminate a VPN on the device. (Possibly my most silly use was to provide a network connection via a phone wifi hotspot to a wired network appliance). And size-wise it's about half the size of a cigarette packet. (Yeah - that feels like quite an odd size comparison...)
