Shattered too  easily

Glass is just too thin...shattered after just barely bumping into a door handle

Absolutely stunning, but so fragile. My top already shattered.

This is so beautiful, but far too delicate for it's intended purpose.  The stem should be thicker.  The nice thing about glass is it is truly clear.  There is no colored hue like I've found with the plastic ones.  Even with careful use, this broke the first night.  I'm just glad it didn't break in the glass punch bowl.  It would have been a shame to have to throw all of the punch away.

We have several ceramic knives and understand that they can be fragile compared to metal, but this one shattered about a month after we bought it while chopping vegetables. Perhaps we were unlucky or it was defective, but I'd expect a ~$40 knife to be slightly more robust.

This was a ton of fun making, but it's just one drop away from being shattered! So careful where you place it.

I have had this case less than a month and dropped it getting into my car. The glass hit a rock and shattered. Now it is no longer useable.  What a waste, I could have bought a cheaper case for the same outcome.

These lovely glasses should be saved for the most sober occasions as they are delicate and quite fragile.  For everyday drink ware, especially involving any alcoholic beverage, they are out of the question.  After a few of my popular Tequila Nuclear Options during our neighborhood game night, it quickly became obvious these were not going to make it beyond the last round of Twister.  These shatter if turned over on a cocktail table or even dropped a short distance on our very plush carpet.  The next morning at least one was broken and another cracked when they simply bumped against one another in the kitchen sink.  The durability of these glasses is quite disappointing indeed!  However, I still award three stars for their beauty, price when on sale, and the several compliments I received on them from guests in the early evening before our last Twister challenge was canceled due to the danger to bare feet.

I loved this container for the few months I had it before it was knocked over at work and broke. I suppose I'd say it's not very sturdy, as it was knocked over from it's sitting position and the interior glass shattered. The outside was fine, but...I found it surprising it being knocked over was enough to break it.

Unfortunately, it fell off my desk and cracked so easily! I thought it would be okay, but the coffee leaked out. I loved the look of this mug and thought it was adorable, but was so sad that it broke so easily.

It does a good job but the glass is so fragile. I just knocked it over the countertop and it shattered. I won't buy it again.

It kept my phone screen from breaking, but this glass broke very easily

LOVE the bottle but it's not tempered glass so it broke very easily and shattered into a thousand pieces when it fell over.

arrived with the glass shattered not into hundreds of pieces, but literally into dust that has created a hazard in my home.

I put this screen protector on my daughter's iPhone as soon as she got it.  Two days later, for reasons she cannot explain, she took it out of the case and put it in her sweatshirt pocket.  It fell about a foot onto our tile kitchen floor, landed on its edge, and, despite the screen protector, the screen shattered.  Two days.  That's all it took her to kill her iPhone.  The screen protector won't keep your screen from shattering if the phone lands on the exposed edge, so although I don't entirely blame it for the breakage, I can't give it more than two stars.  Keep your fragile, built-to-spill iPhone in a good case.  Better yet, get a phone that has something going for it other than fashion.

Very fragile, I had only a few months and they completely shattered. Not meant to be used as an actual cup.

I purchased this in December, 2015.  I liked the product for the reasons others mentioned - it seemed well-made and quite bomb-proof.  While it is very heavy, and the metal scratches quite easily/ the paint chips off, all of these seemed like worhtwhile trade-offs for the protection. The built-in glass screen protector is no good.  It interferes with touch screen function, and after a drop, it shattered into dagger-like shards.  I replaced that with a .3mm tempered glass cover, which worked fine with the metal case, but in doing so the case was no longer as water-resistant.

The combo of the case with an after-market tempred glass screen-protector worked well for a while.  In fact, a car backed up right over it, and the only damage was to the screen-protector, which I then replaced.  Which is why I was shocked recently when I dropped the phone on a linoleum floor, and when I picked it up, the screen-protector was UNBROKEN, but the screen itself was completely shattered UNDERNEATH the screen protector.

So it lasted about 5 1/2 months.  Oh well, I'll have to look for something else.

The silicone covering didn't protect my bottle. One drop and it shattered.
