I purchased these in both sizes & they fit perfectly into both size mason jar lids.  They provide an air tight seal for transporting liquids.  Make sure you do not over tighten the lids or they will be nearly impossible to remove!  I've used these daily for about 6 months now & they look like the day they were purchased.

It been a year since i bought these, and they still look great!! They are starting to get loose on their own now though and have to be retied every couple of hours.

Still look great after six months of almost constant use. No problems so far. Comfortable and love the directional pattern so I'm not constantly trying to figure out which way they go.

--update--
Still looks nice and haven't had any issues with the elastic wearing out after a year.

I LOVE these, I have worn them almost every single day since my purchase (11 months ago), most the time I sleep and bathe in them.  In the time I've had them they've shown no obvious wear. Honestly I'm tempted to buy another set to have as a "backup" because I really like them that much. Since I primarily wear gold or silver jewelry and accents I can just switch which way faces forward depending on what I'm wearing.

With near-daily wear, they last me about 6 months.  After that, I can tell they need replaced by the ache in my feet!

Will buy again in a larger size, for other than just daily use. I've been wearing these for more than six months now and I never take them off. They stay the same color and the screws have started lightly to give away which is a bummer, but for the price I'd buy them again.

After six months of daily use, my husband's boots are usually starting to shows holes in the sides as well as have a worn out sole. It has been over six months and these are still in great shape! Hubby says they are comfy too! Will plan on ordering again when his current pair wear out!

I purchased a set of these in Feb of 2016, so we are at around 9 months and they are holding up spectacularly! No rust or discoloration, they've not bent or come apart anywhere...they look just as good as they did the day I purchased them! I have white porcelain enamel sinks and wish I'd invested in these far sooner than I did, they save the day when it comes to scratches and chips in the enamel, plus they do not catch food or residue the way rubber mats can...everything rinses down the drain easily with no fuss. Honestly, the look far classier too. I highly recommend these!

I've had this for 7 months, use my iPad daily & it still looks just like it did when I purchased it. Great quality, great price!

With fairly heavy use (about 30 hours per week), these appear to last about 6 months each.

Assuming they are not lost in the meantime, I now have a supply that should last until 2020.

Good Deal!

Still loving this calendar. Been buying them now for 6 years and I'm not tired of them yet! :D

I've used this every day since purchasing, and it still looks like new

I've owned these for upwards of 6 years and they still work perfectly. They see anywhere from 1-10 hours of use per day every single day, so I'd say that's pretty damn good. Excellent quality for the price, and I'll probably order another pair once these shuck out.

I ordered these in back in August 2014. They are my every day use headphones at work. When they arrived, I charged them once for the recommended amount of time and then jumped right into some tasty jams. What's strange is that was the last time I charged them. I don't know what  kind of sorcery is powering these things, but they will not die. I would have given them a 5 but they look kinda goofy on my head, so -1 for aesthetics.

Use this daily, still looks brand new after months and months of use

I must have bought these at least a year ago and I am still using them regularly without any issue.
