Update 2024 05 23, reporting on my experience with my just decommissioned, fifth windsock. So one of these windsocks lasts for a year, generally April to April down on my dock on the Lower Appomattox River. They can start to look a little ragged by six months, but still be useful up to about a year. I've attached a dated picture of last year's, which I just replaced after a year. (Attached from a previous year is a new one right after I put it up.) For the price I think these are a good deal, but after a year of use, expect to replace it. As I've noted previously, sure to keep the clip; they last forever and can be handy. See you next year.**************Edit 2023 04 03: Just put up number five. Raising rating from four stars to five. The value you get for the cost is decent. The lifetime of one of these windsocks is very predictable here on a fresh water (but tidal) river in the mid-Atlantic: one year.  I've just replaced the previous year's windsock with this year's.   I do this right on or about April 1st each year.  My two windsock pictures show last year's and this year's, photos taken less than three minutes apart today.  You'll be able to determine which is which.  This same scene has happened every time in early April since 2020. (First one went up in April 2019.)   I find this satisfactory.  My windsocks are subjected to nearly full day sun and a fair amount of wind Sept through May.  They fade noticeably by late fall, and start to shred by late January or early February.   My third picture shows a little bonus you get.  When you take down last year's windsock you should harvest the stainless swivel clip.  It's good quality and can be handy for working with 1/4" rope, say for tie downs.Edit:2021_04_27 update. I've just discovered I'm buying one of these a year, just about to the day. As noted below it lives 24/7 at the end of a dock out into the Lower Appomattox River in SE Virginia. I've posted a photo of #2 which I just swapped out with #3 about an hour ago. As you can see, at least you get a nice stainless clip to keep at the end of the year. Despite its short lifetime (and serious fading) it's still worth the price in my opinion. I'm not sure what material would do better.Mounted first one down on my dock in the river a year ago. It saw all sorts of weather while there: lots of sun, and varying winds. It gave me the information I needed for deciding whether to go out for a sail. It did fade pretty badly over the year, except the reflective bands held up pretty well. (They reflect well in my dock security cam's IR at night.) What did it in was 60MPH wind gusts with golf ball sized hail in a Tstorm about a month ago. It was ripped open in places after that. So what did I do? I bought two more. At the price, getting a year out of one of these seems reasonable given the conditions it has to exist in. Oh, and the swivel hook for attaching it is a nice feature. It keeps the attaching straps from getting all wound up.
