Yes the Vello freewave looks like a great device. I'll have to think about how much I might use it before purchasing one.
An alternative if you already happen to have a cellphone/tablet, two cells or two tablets (Android or iOS) with Wi-Fi direct is TriggerTrap. You attach one device to your tripod with the TriggerTrap to camera dongle and use the other device over Wi-Fi to execute your TriggerTrap commands. Of course you can use TriggerTrap with only one device, but it won't be wireless. TriggerTrap also has a big library of exposure options taking advantage of the various sensors built into your cell or tablet.
Another advantage for me is I generally have both my cell and my tablet with me when I travel and I am only adding the incremental size & weight of the TriggerTrap dongle to my camera bag.
