It was great until the glass top broke before much use.  I can't find how to contact the seller either for this product.on Amazon, have to keep digging.  Shouldn't have to be this hard to get a replacement for defective glass!!

Lid worked great before it broke. Trying to lock the lid back so it doesn't smack you in the face while you take a drink was always more difficult than I really expected it to be. The other morning when I went to lock it, the plastic hinge snapped. I might buy another one here soon, but I'm pretty disappointed it only lasted a month and a half.

The plastic tab on the cap that holds the thing shut broke just over a month into use.  It got dropped from a height of less than 4 feet, and now it's useless.  It was super great before that though.  Kept tea hot for 24+ hours.  But you have to treat it as if it's made of porcelain, because it's apparently pretty fragile.  I don't understand why the cap isn't metal.

This was an awesome waterbottle.  I seriously loved it. But I was sleepy walking to my Barre3 class and didn't realize the top wasn't totally screwed on, it dropped in the parking lot, glass lip side down and broke. On the plus side it was easy to pick up ( just in case you make the same mistake)  the rubber sides kept it mostly together but alas... I cannot trust myself just yet to replace it

I loved this grinder. The biggest selling point for me was that there was no mess in the cabinet or on the table. But as for many other people, it broke. I had my grinder for ~4 years before the top separated from the bottom. I wrapped several yards of Teflon plumbing tape around the grinding mechanism and pushed the top back on. It seems to be holding fine, but this is only a temporary fix. Still, it took 3 minutes to fix and if it lasts another 6 months before it needs more Teflon tape, I am OK with that rather than buying a new one, as the grinder mechanism still works great.

For the most part, I am happy with it but this glass did end up breaking within six months.

The cooktop itself works well, delivers heat very evenly and fast.

The primary issue we have is with the glass top itself. It's very slick, which will cause a pan or pot to slide around on you when you're stirring. Also, after about 4 months of use, there's a 3-inch stress crack a few inches in on the glass. It looks like a hair stuck on the glass, but rubbing your finger over the spot lets you know it's clearly cracked through. Nothing was dropped on the cooktop, there's no point of impact, no lids left to cool creating suction, the glass is just very fragile. Maybe next go around I'd look for one with a textured glass top, maybe one with more durable glass?

Overall I'm glad we have induction, it's fantastic, I just wish it were a bit more durable.

I absolutely loved this Kettle...but we've had it less than a year and when the spout hit against the backsplash after being accidentally bumped, it broke off. =( We're really sad and now we'll probably be getting a stainless steel replacement so we don't have to worry about it breaking if it gets bumped.

I bought this and loved the product but now the top won't come off  (it just spins and spins) so the contents inside are useless.  The bottle is glass, so I can't break it open.  I looked for customer service, but couldn't find anyone to help me out so I won't buy this product again.  I gave it 2 stars because the content is good, but the bottle lid breaks so the purchase is null and void.

I had this for a little less than two years.  I liked it because it was bright and distinguishable from the other cans on the block, and was heavy duty Rubbermaid.  Unfortunately, the top of the can failed, first on one side, and then on the other.  The first side was not repairable since the plastic came totally off and (I assume) was thrown away with the trash.  The other side the plastic bent and the lid came off all the way.  Now the lid is not attached at all.  We have to keep our cans in the garage (yes, in the hot Texas summers) and it is critical that the lid closes well.  Now I have to replace this after less than two years.  I will be looking for a different brand.

This works great in our Keurig 2.0 . . . until the plastic on the top gets brittle and starts to break apart.  I super glued it back together but eventually the dang thing's toast.  This happened with an earlier one I bought and I figured I'd give it another shot, but apparently it's a design flaw.  should have a metal top that doesn't degrade under repeated heating.  Fix the problem Keurig!

I had one for a few weeks and I love it for the most part. The mouth opening is perfect for chugging and I love the color and style. I went to the pool with it today and it lightly tapped the bottom of it on the ground and it shattered it! I feel this needs the be a thicker more durable glass and or more thick silicone to protect it. For the amount this bottle is, it should not break as easily as it did. I feel life factory water bottle glass is more durable than Konrel. I'm thinking to order another one but I will have to babysit it because it breaks easily.

I agree with other reviews.  This is a great stovetop coffee percolator HOWEVER, I also agree that the cheap plastic piece dumbs it down.  I've had mine for about a month of daily use and the plastic piece started to leak and as of today broke off.  Although I'm now ordering a glass piece to replace the broken plastic piece; it should have been glass in the first place.

Loved this bottle when we first got it. Well it's less than a year and the top doesn't stay screwed on, or the threading is defective. Not sure what the issue is, but it's time to purchase another type. Other than this flaw, it does spray well, it's a sturdy bottle, but top is not secure rendering it useless.

The glass part is great - heavy and good quality.  The top part is a very cheap plastic, I think.  Whatever it is made of doesn't matter.  It feels like it will break after not being used very long, and it leaked each time I used it.  And I don't mean that you use it and there is a little drip of syrup in the front - I kinda expect that.  I mean I would use it, make sure there was no syrup drip on it, put it down on the counter, and then come back later to lift it up and find a small amount of syrup on the counter.  This happened every time I tested them.  I sent them back, and found a different container in a store that works fantastic.

This press made the best coffee, so good I was able to overlook how annoying it was to clean.  Unfortunately, as so many others have pointed out, the glass is extremely fragile and all it took was a slight bump in the sink and it cracked.  I'm replacing it with a press of more sturdy construction.

Nice features, appreciate the nice glass container, but broke within 4 months of regular use.
