It's the one I use, I can't note any flaws or user problems...it's very versatile. It will even fit onto a 1/8 wing mount (using the supplied wrist strap) which is handy for confirming speed in your truggy/buggy...it sits in there beautifully & is protected for all but the most severe crash
Here's a 'size' shot from my Rustler. You'll note the sophisticated rubber band mounting system!!
