Flat after a few years.

This pillow started out to be a high loft.  I felt like I was laying on a balloon...with the awful synthetic smell and all.  Now that I've had this for a few years, the pillow is flat...but, still supportive.  The chemical smell is still present, though not as much as it was when it was new, but I'd have expected this to dissipate completely after all these years.  No such luck.  Would I buy another one of these pillows?  No...simply because of the high cost of the pillow and the fact that it does not hold its height...and because I'm thinking the off-gassing this pillow does can't be good for one's health.

For the price it worked for a while and after a year or so had enough wear to toss it.

I bought this humidifier less than two years ago, and have used it only a dozen or so times. It worked fine for a while and then... it didn't. The fan still works and the filter is fine, but it just stopped producing humidity. The warranty is only one year and the window for returns has passed, so I'm out 60 bucks. Save your money.

I thought an expensive latex pillow would avoid compressing like traditional fiber fill pillows and that this would be a worthwhile investment. Unfortunately I'm not so sure about that now. I've had this pillow for 3 years now and while I love it, after about 18 months it was noticeably flatter (I had the high loft plush version). I've been sleeping on two of them stacked for the past year and I'm pretty comfy like that, but at $80 a pillow I was hoping they would last longer before getting flat.

after a few months of use, the insert has flattened, and more particularly, indentations where the big toes are so it has gotten somewhat uncomfortable to wear for long periods

Still performs well after a few years of use, but developed a white, powdery layer after sitting for a while.

We bought this a few years ago and still use it but unfortunately the top part no longer stands flat. Actually this happened after a couple of months we bought the product; probably an over pressure or heavy load to the top part. I tried to fix it a few times but everytime it lasted only a few days and the top is loose again. When we use it now, we get support from the coach to hold the top part as flat as possible.

kinda cheap but it served me well for 2 years in a tight space as a roll-away laptop desk & misc. flat spot

Well it was nice while it lasted. 3 years. Maybe that is the life of the product. Not sure. My husband has his luggage from 20 years ago. Just don't make them like they used to. Wheel broke. Hoping to find replacement pieces.

I have owned this for 1 year. After 6 months there was a distinct depression in the middle of the bed. It has only gotten worse since then. If the price is cheap enough, I would view this as a stop gap/short term solution to finding a better mattress.

Functions fine, light weight and have had minimal flats after going through about 6 of these through the years but the life is not very good.  They seem to wear out much quicker than other tires I've used and I'm not a heavy person.  I deducted 2 stars for the life of the tire alone.

I bought one of these a couple years ago and I think it was better.  This time it felt thinner than before.  The last one lasted a couple years.  This one died in a month.  Almost every single bubble has gone flat. They look vaccumed in.  It's worthless now.

It started looking old and worn after only a few months

Bought this with 3 accessory handsets in 2008.  Was awesome for a few years.  Then the "cursor"(?) button on all handsets failed, but it was still decent because everything else still worked.  In the last several months, (2016) all the handset batteries are failing, or maybe it's the chargers, I'm not sure.  I now get somewhere between 6 and 20 min on a "full" charge on all handsets.  And only sometimes do I get a warning beep before my phone dumps the other party.  Overall I'd have given them a better rating, if I'd been fine with them being only fully functional for a few years.  Definitely got my moneys worth out of them, but if my experience is at all typical, you basically have only a few years of full functionality with this set.

I bought one of these three months ago, and it worked fine for about two.  However, even though I am not an especially large person, this cushion is flat now and is no help with my sciatica anymore.

The PharmMeDoc cushion I bought at the same time is still going strong, though, and I will order another one of those to replace this.  The foam on that one has held up much better.

Lasted a while,  but did start to deteriorate,  so had to replace after 1yr.+

Its ok...it stopped working after a few years, but while it worked it was good.
