Seeings how this is also a doppler radar, I don't expect it to be any less "fussy" than the LabRadar.
It has a smaller antenna and less power but also does not attempt to track the projectile continuously out to 100 yards.
Guess we will find out from the first few users reports.
It sure looks handier to set up than the LabRadar mostly because it's smaller.
It better be good given the price.
When it comes to fussy I would rate the optical chronos at #1
Then the magnetic and radars.
Their operation is so different it's hard to compare "ease" but once setup and running the Magnetospeed is the easiest of the bunch to use while shooting.
I'd use it more often if it didn't have serious limitations as to which weapons it will work with (no double barrels, pistols, or short revolvers).
And forget shooting for groups while chronographing too.
I have fitted it to a 3" 696 but that's pushing it (see picture).
They all have shortcomings as rockquarry has mentioned but the LabRadar is the only one I use now as it has the fewest of those shortcomings and gives the most data.
It's the only current chrono that will give you the real BC of your load at a given range (without setting up additional equipment downrange).
I don't see the Garmin doing that.
There are a couple of reviews already on the Tube:
