Have both my Tech and GMRS.
I use my amateur radios almost daily.
I only use my GMRS when doing something like Camping, Geocaching, Hiking, Off Roading.
To be honest, I have shitty Cobra Bubble packs that aren't programmable or Repeater capable.
Also, we have no GMRS repeaters within 80+ miles of us that I've seen on any official listings.
The neat/positive thing is, I have scanned 24x7 for weeks and every so often and never heard a peep in my AO.
So that means, I pretty much have multiple wide open, uncontested Channels to use when we want to use them, providing we stay in acceptable range of each other.
Worth while or not depends on each users needs and expectations.
If the range will work for you, then they are awesome, cheap and easy to use. Even the programmable ones and Chirp.
Many are looking for a bit too much, range wise for GMRS and too me fair, Many are looking for more than they'll realistically get out of a 2m Simplex set up too though.
Needs, Range and Wants? Those are they key questions each person or group needs to ask themselves. Is this right for me.
