Arms Compatible with 25mm or 1" Ball Systems.

This product is very sturdy and probably last for ever but is is heavyweight.

I am new to these ball mounts but I'm loving them. Already bought a set for my other pickup.

Nice but heavy. I wish it was drilled out with a bunch of holes to shave weight

Very solid, great quality

I purchased this mount to complete a common Tacoma mod - called the "A-piller Ram mount phone holder" and I Love almost everything about this little 1" ball mount. Key word almost! Some folks have complained that the standard mount brings the phone too close to the steering wheel, so with this version having a swivel, I thought it may be a more adjustable option than the plastic Ram branded version, and I was right.Pros:- All metal design is quite rigid, does not shake at speed or over rough terrain, and should definitely stand the test of time, no concern about brittle plastic after years in the sun.- Has the capability to swivel at the mid-point, allowing you to position your device in literally 2X the number of positions as the standard RAM mount of the same size. (This is the #1 reason I chose this design)- Tension knobs are very rigid and do a great job of locking the swivel ball mount in it's intended place.Con (if you can call it that)- The cups that grip the 1"uniball are quite robust which is great, but they have maybe a bit more coverage than necessary, which does limit the maximum angle that you can set the swivel at when mounted. This is such a small issue that it almost doesn't even matter, but if you are mounting in a tight location it may pay to sand/grind a small amount of the lip away to provide a few extra degrees of adjustability. Again, so minor it won't even affect most folks.Bottom line is if you are on the fence at all, this is the superior option for a mount this size and style.

Strong and sturdy mounting arm and the rotating feature is superb. It allows me to place my phone holder in the exact location I want it that's not possible with standard non-rotating ones. It's got some weight to it and the material feels and looks like a good aluminum alloy.I struggled with keeping the arm locked in place initially and it would slip on the rubber balls, I actually took it off due to this and then tried again a week later but cleaned the mating surfaces and the ball with alcohol to see if it did anything, and there was no more slippage so make sure you clean all the mating surfaces if you don't want them to move.

Same as a Ram Mount extention arm for all practical reasons. Just cheaper.

Works just as good as the RAM version. Don't hesitate to save a few bucks. My only note is the gauge of the spring on the tensioned side. This one is thinner than the RAM version and buckles sideways instead of staying rigidly centered. Still does the job, so no worries.
