Our house was resided last year and so the flag had been taken down for a while. It's gone back up and I quickly remember how often I was out there unwrapping it from around the staff. I had used the spinners before but they were made of plastic and the tabs quickly broke. Found these, they got good reviews and decided to try them since being made of aluminum, they would be much more durable than plastic.

Overall, they do work quite well. In light winds, my flag can still get 'flipped up' onto the staff by the last puff of air but usually fixes itself with the next breeze. I have a polyester flag (in the reviews people mentioned lightweight polyester as a problem) but it's not a particularly lightweight fabric in my opinion and it may be why my works quite well.

They've only been on for a few days so I hope the long term reliability is good, I can't comment on that yet. Durability rating is to be seen.

As others have posted...the weight of the flag is critical and in there is the issue no where could I find what the recommended flag weight should be for these devices to work. I also purchased a new FMAA cert. flag approx. 3x4 but it's not heavy enough and it's not a cheap $10 flag either...The free spinning design is just not free spinning enough...I guess you need a 10 lb flag. The quality of the device is good and the price reflects that...It's been about 14 days and I have had to unwrap it at least 10 times. So I am disappointed it does not work any better than what I had before which was the kind that the flag had a plastic tube that it spins on.

Update: I read on another post to lower the top spinner about an inch, this gives a little slack as the flag hangs...after doing this it appears to be working much better. I am changing my review to 4 stars. Suggestion to the manufacture: things like flag weight, different placement of spinners etc. should be included with the product as things try to improve performance. The instructions that were provide had very little.

I've tried three similar types of flag swivels - all of which crashed and burned because of poor design or manufacturing shortcuts. These are designed right and built to last. I fully anticipate replacing the swivels on my other flagpole with these and not having to change or repair them again (maybe lubricate occasionally).

These Non Tangle Flagpole Swivels work great when you know what the trick is to get them to work properly.?
The instructions specifically say which direction to mount the swivels on the pole. I installed them as per the instructions. They worked great for 2 days. After that, the flag started wrapping and twisting itself around the flagpole. I constantly had to go outside and unwrap it.
The swivels didn't work any better than the original plastic ones!
I double checked the instructions to see if I overlooked a step. That wasn't the case. I installed them correctly.
I tried everything, including re-adjusting the swivels to either make them closer or further apart from each other. I gave the bearings a shot of WD40. Nothing helped - it still got twisted.
I finally solved the problem by turning the swivels in the opposite direction that the instructions said to.
Eureka! That did the trick! They're working perfectly now.
One other issue I have is that the size of the swivels won't allow the flag to fit or slide over them. It takes a little more time and effort to change flags, but well worth it. Far less than what I used to spend with the original plastic swivels.
The product itself is quality made to last forever. It's heavy duty/commercial construction is far better than those cheap and poorly made imports on the market.
This is an American company manufacturing a great product, here in the United States. I highly recommend them!

Works well
