Weaknesses: (extended from above)
Label paper MAY shift making guague impossible to read (I hope not!)
Price (Like all DYE items and all Mini Guages)
Nickel Plating is cheap and thin, can be easily scratched
Too rounded: Wrenches can slip on it
Well I bought this to fit into the front block of my cocker, but due to the 15 degree asa the gauge interferred with the seal on the block. I eventually screwed it in a few more rotations to get the clearence necessary, and the front block is no longer leaking. The guage is small and unobtrusive, but I hope it doesn't start to misread like so many other people's.
I'll say this is an above-average product for me (so far).
