Going on 7 months now. I'm very impressed and happy with their performance and by how much brighter the cab is now.

I haven't had mine quite a year yet, it's been about 9 months or so that I've had mine but they're just as great as when I took them out of the box.

No I have had mine for several years, since 2011 or 2010. But they are in the dining room and aren't used daily.

A LONG time. It was years before I had to replace mine, but I don't use it every day. Maybe a couple times a week is all.

You can use them many times until they wear out. I have had no issue with multiple uses.

Not sure how long they last. But I have had mine a few months with no issues

Not enough time put into using them to tell just yet, but they have lasted just fine for the amount of time I have used them. Which for reference is maybe 40 or so hours since I got them a few months ago.TL;DR They seem pretty reliable so far.

They are designed to last approximately 30-45 days. However, I have seen customers that have gotten much more time out of them. An average usage time would be about 2 months.

don't know. When I buy them they are usually good for 6 to 12 months or longer.

When I first used them I changed them at 90 days. But over time I noticed that they were not that dirty after 90 & I have left them in longer. I change them three times a year now.

They're good for about three years. They only last about a week so that's plenty of time.

I had that happen when i first started. They probably will even out. How long have you took them??

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

I don't remember. I think 1 year. But I've had mine for at least 2 years and they still work great.

I've been using mine a few months, they don't seem to be wearing down. I bought a second set!
