At first it was great, but over time the notches were loosened with use and the whole thing would slide out of the vent and would fly across my car (after about 6 months of use). I also didn't like that I had to use 2 hands to put my phone in and take it out. This was promising but as soon as it kept falling out of the vent and my phone was in Jeopardy I switched to a magnetic phone holder.

I initially really liked this harness.  My dog walked great on it and it significantly reduced his pulling.  After about a month or so of use, however, I noticed a bald spot forming on the lower part of his chest right above his leg.  The front has a tendency to sag, especially with a heavy leash, and I tolerated it in the beginning but it got more and more annoying.  No amount of tightening and adjustment could resolve the issue.  The bald spot continued to grow and I finally had to retire the harness and try a different brand.

Great while new, but after a few months the usb ports got loose!

I loved this otterbox, it worked very well to keep liquid out and protected my phone well. About two months ago, it started losing its shape and it all went downhill from there. It now has pieces falling off and is stretched out in several places.

It worked really well for the first couple months, but the part that grips the vent loosened up too much to be appropriately snug and stay on now.
I would keep an eye on that and be very careful handling it. It is essentially gone for me now, but perhaps I was too heavy handed with it.
It's cheap, so it's a decent buy. May not last long.

I've been wearing this badge daily at work for the last 10 months. I liked it at first quite a bit and got a lot of compliments on it. However, over time the silver parts of the necklace have become tarnished and look gross and shabby. I've also had to fix it in two different places where a link became stretched and the necklace would break apart. That's not really a big deal, happens with wear when you catch your badge on tables or your desk. But the tarnishing is disappointing. Guess I'm going to buy something new.

I've had this chair for close to a year and it was great in the beginning.  Now I have three problems:

1) I like to keep the chair at its maximum height but unfortunately it won't stay there for long.  It slips down to a shorter position requiring me to constantly raise it up

2) There are now squeaks all over the place.  I can't be on a speakerphone conference call and move in the chair because of the crazy noises it makes, particularly if I try to lean back

3) The backrest is now pretty loose and wobbly despite tightening.

Having said those things it was a great price and is awfully comfortable.  I could handle the squeaking but have no idea how to remedy the vertical height slippage which drives me crazy

It worked great for ten months of infrequent use - but now the ball joint has become loose. The holder and my phone bounce all over the place now. I don't understand this.

At first I though WOW this is really nice. Then, after 5 mos, it started to fall apart. The trim around the edges all peeled off, and it now has a sharp edge. Also, the cover became a little bent, and so the kindle doesn't go to sleep when the cover is closed. Currently looking for a new one, but probably not this brand.

It worked great for a little while, but now, after a couple months use, the bolts that hold stand in position do not hold anymore.

This lift was wonderful when I first got it. It was bright, could be adjusted in height, etc. after a year, the screws on the light which sets it in place became weaker. Now the light randomly falls down and isn't much use.

I initially loved this bag, I'm a huge fan of the Grid It system.  It fits everything well.  However, starting maybe 6 months in, one of straps started to literally come apart at the seams (see attached photos).  For a bag that I paid $75 for that's pretty disappointing.  As you can see in one of the photos, I put some superglue on it hoping to keep the seam from splitting the whole way down.  Other than the seams coming apart, I have really enjoyed this bag, nice and slim and holds everything well.

It's made with a lot of good-quality materials, but after ~15 uses some of the pieces started to detach, so I had to dedicate 2 hours or so to see what was happening and fixing it.

Started out great, it is very helpful. After about 3 months of use the usb c plug started to get questionable and is now at the point where it is unusable. The plug has com completely loose, looks like the metal snapped inside. Hope in future models, that this is reinforced.

While it lasted it was great but eventually the plastic on the inside disconnected in certain spots and I had to toss it.

It was great in the beginning. But after several months, the material gets flexible and every so often the corners slip off

Was very pleased when I first purchased this product.  About a month later however, the the cross dividers began seperating from the other dividers.  As a carpenter, I was able to fabricate new pieces to brace the cross pieces, which I glued and nailed into place using a pneumatic brad nailer.  Now it works. Also, the knives had a nasty habit of sliding under the dividers.  If possible, vinyl would be a better choice as it is formed from a single piece of material.  It cannot fall apart.
