Do they wear out ?If so how do you know?

I don't know if they wear out but there is a red light on the front so I guess if it stops working the light would go out.

I had 2 that were still working for at least 7yrs. I've since sold that house, so don't know if they are still working. I guess if the bugs come back, then the unit is done and need to purchase another.

I bought the 3 pack over 2 years ago and 2/3 are still working as far as I can tell. In the last few months the red light on one of them stopped working so I threw that one out and the other two seem fine. I'm a believer :)

Don't know but I imagine that they will eventually wear out. So far working well - the red lights let you know.

I don't know. I purchased them this year to replace my 9 year old ones because I noticed more insects (flys lady bugs etc) this springI plugged the new ones in and the bugs went away. Callme crazy but I think they work

I have no idea if they wear out. A red light is on while plugged in, not sure if that is a "power" light or a "working" light.

They don't wear down. They can break off but if you don't apply pressure, there is no need to worry. I frankly am not that enthusiastic about them because you can control the width of lines in most apps anyway.

They are tight until you have used them for a while and they wear in a little.

Only as they wear out. If they no longer fit good or are performing good then replace them. Other than that they don't need to be replaced very often at all. The valves do have a tendency to wear out quicker than others.

I have had mine for about a year. I use them on a pair of shoes that I love, and pretty much wear every day, and they have held up well. I suspect that they'll outlast my fraying shoes at this point.

I've worn mine 3 days a week for about 4 months or so now for Strongman training and they have almost zero signs of being worn. Great product!

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

Mine have lasted and are one of the best things I ever bought. I have one pair for my mattress cover and one pair for my fitted sheets.

I've used them several times and there does not seem to be any appreciable wear on them

I've had mine for at least a year, maybe nearly two now. It's out year-round in NJ weather and there is no wear at all.

I've only had them for a week...but I wear them for about 9 hours. I'm ready to take them off at that point. But so far, wearing them all day hasn't been a problem. Buy them - they're great!

they last a while if you dont take it in and out of jean pockets. otherwise just normal wear and tear

They are quite soft and while a sock keeps them in place, they eventually get deformed and become useless. This is just normal wear. For me they last 6 months or so before replacing with new.

I've worn them daily for as much as a month with no problem. I usually swap to a new one at that point, but that's an arbitrary thing -- they still seem to work well even at that time. Eventually, though, they do get stretched out of shape and don't do as good a job of supporting the knee.

I have yet to replace mine. As long as you wash, dry & power them they should last quite a while.

No. I honestly cannot tell the difference other than I think they wear out a little quicker.
