As a LabRadar user, I've basically had two main challenges with it.
1) The interface is just bad. (fixed by new Bluetooth App?!? Very excited by this development)
2) Mounting it. The darned thing is huge, and top heavy; basic inexpensive tripod systems struggle to securly hold it well, and keep it well aligned. Short answer, after trying a bunch, here's what I've found to be the best low-cost mount for my LabRadar.

It's $20, and uses a high strength spring that you depress with the button, rotate the ball as desired, and release the button, and it locks into position. Most tripod mounts have wiggly legs, and way too weak of a ball/spring system - and this is the only one I've found so far that actually works.
I have had a few other oddities with the LabRadar. It's... finicky about memory cards. Sometimes they just lock it up and it won't work at all. I have one that works, but it slows down my LabRadar by about 4X normal processing speed - not really sure why. Again, hopefully the new BlueTooth app will eliminate the need for a card at all now, and fix that too.
