well, on topic. I really like my reeflink. But, to be fair, I have no experience with the WXD. I guess a matter of opinion. If you already have the Apex, it may be better to avoid one more piece of equipment. For me, I wish ecotech would come out with some more options for reeflink. A controllable programmable power strip would be nice with some monitoring. Basically, I wish they would market a controller to go with reeflink.
To be honest, the reeflink was a pain to set up at first. one of my vortechs would not take a fw update the first like 10 times I tried. But, once it was all set up, been rock solid since.
