My impressions so far:
Definitely have to read -- and remember -- the user manual carefully to understand exactly what the various status lights indicate. Basic operation though is pretty obvious: press the on button and then press whichever of the other three buttons you need.
The belt clip does not inspire great confidence, but it can be backed up using a lanyard (which is *not* included) to girth hitch the Spot (which *does* include a lanyard attachment point) to something/somewhere else. Alternatively, the belt clip can be removed entirely quite easily. (The same style of attachment/removal screws are used for the battery compartment -- quick & easy to remove, yet very secure when attached..)
I called customer service at a little past 8pm eastern time on Christmas Day and immediately received a very helpful & friendly agent. My inquiries and responses were:
-- "The online account seems to provide for setting up more than one messaging/notification profile (i.e., so instead of having to edit all the info, can just switch back & forth between different profiles), but how do I add profiles in addition to the default profile?" "This seems to be a placeholder for a feature to be added in the future."
-- "Are regular alkaline batteries ok to use for testing purposes (i.e., to save those pricey lithium batteries, one set of which are included)? (The manual and unit have warnings about how they can cause damage.)" "Yes, sure, okay for testing purposes, although won't last as long for real field use."
Some screen captures from initial experience follow below.
Online account setup screen for messages and recipients:
Gmail inbox (note that sender name and subject header can't be modified, and both have a somewhat spamish aura):
Message from Okay signal activation:
Screen capture of what happens when an email recipient clicks on the provided link (can be zoomed and moved around like usual in Google maps):
Messages from three separate Help activations -- the first two were sent outside, then the third was sent from inside a house with only relatively limited windows (GPS coordinates still went through, but no info on nearest town -- can't figure out if this is some weird coincidence?):
Messages from two separate Help cancellations -- note that these messages never seem to include coordinates (which I suppose serves to emphasize that the sender does *not* need anyone to come out to the sender's location):
Online account message history:
Online account map view (with all messages selected -- can include just some subset):
