Excellent addition to Spyder Cuff
I added this to my Spyder Cuff to hold Lamonster's metal phone holder. Works great, but wants to loosen. Will put a bit of loctite on the threads when I get home.

RAM 1” tough ball base
Just what I needed. Wish it had been available at dealers parts department

Ram Ball
Exactly as advertised, works with all the other RAM products I have and threads into the cuff perfectly.
-
Ram Balls
I bought the RAM balls just in case I want to add anything to the mirror top mounts like a drink holder or cell phone holder. Inexpensive and better to have them on hand just in case.

PUT BLUE LOCTITE ON IT!
After installing it without any thread locker I found it to work loose in a short amount of time. I put some blue loctite on it and cinched it down and let it sit overnight and no problems so far.

SPYDER CUFF
This is an excellent product. Fits well, looks good and works well. I am using it to mount a GPS device. It is quite easy to locate the device so it does not block views of rear view mirror or instruments.
