- Reviewed in Canada on August 14, 2020Verified Purchase1/31/25 Update
I have been buying these glasses for years. It takes a lot to break one. They are among the most solid glass glasses we have owned. It doesn't mean they can't be shattered. When they drop from a height onto ceramic floors, there is a 75% chance they will shatter and a 25% chance they actually won't which is quite remarkable. Anyway, my husband broke one recently with a long spoon. We all love these glasses though so there was no question we would replace it. They are workhorses in our house. They are our go to glasses for a cup of hot tea with cardamom, a glass of ice tea, chocolate milk, just about anything. The hot stuff stays hot longer, the cool stuff stays cool longer, there is no sweating around the glass so you can put them down anywhere without it leaving a stain, they are so big that they match most tumblers in size except those new McMansion ones. I really can't say enough positive things about these glasses. When I use anything else, I feel like I'm missing something.
10/14/2023 Update
I think it has been several years since I wrote my last review and I don't believe we have broken a single glass and we still love them. They are perfect for hot and cold drinks and can easily hold a full can of soda with ice. I still appreciate that they don't sweat when left on a wood surface like regular glasses do and they keep everything hot or cold longer. They are the best double-walled glasses I have owned and I purchase many different ones because I like them so much.
Original Review:
I've been buying these for years. We love that they hold a lot, don't sweat so you can comfortably put them down on any surface, keep beverages cold for much longer than regular single-walled glasses. These are heavy and I usually like light, but somehow we all like these a lot anyway. They are the perfect size for breakfast smoothies or tall glasses of water after a long walk in the sun. They're also great for ice tea. I've broken many other double-walled glasses in the dishwasher, but I've never once broken these. They've only broken with high falls onto our ceramic tile floor. My daughter is leaving for university this year and on her "must have" list are several of these glasses. They should be on your list as well.
- Reviewed in Canada on March 17, 2021Verified PurchaseBought 6 of these glasses to replace the random variety of beer glasses we had. These glasses do a fantastic job. The glass is nice and thick and has a good weight to it. Feels like it won't break if you accidentally whack it against something or hit it.
The double wall was a must for me. Keeps my beer cold longer so I don't have to pound it back, and I can take my time to enjoy it. Also no condensation or moisture on the glass when it's holding cold liquids in warm air temperatures.
Highly recommend.
- Reviewed in Canada on May 25, 2020Verified PurchaseWe've had these a few weeks, and so far are really enjoying them. They are big. But any glass that's big enough to hold a full can of beer (even the 500 mL European beers) plus the added space needed for the insulating gap, it's going to be large. But they keep drinks cool for a good long time, which enhances summertime enjoyment.
We've only had these a few weeks, so it's hard to comment on durability, but the glass does seem on the thin side, so we will be treating them with care while washing by hand.
We wanted to buy another pair so we have some on hand for guests, but they're now out of stock. :( Hopefully we can get some more soon.
- Reviewed in Canada on May 7, 2018Verified PurchaseIt arrived safe and sound, there was a dent on the box from shipping and the packaging was good enough that the glasses were no worse for wear, so don't be worried about that. There was some minor imperfections on the rims of the glasses and one wobbles VERY slightly but considering the price and the overall quality, this was a good purchase!
- Reviewed in Canada on June 10, 2025Verified PurchaseLove the size of this. Doesn't feel fragile, but strong and luxe.
- Reviewed in Canada on July 5, 2023Verified PurchaseI dont like having all this glass just waiting to break. They would be much better if they had a lid. Keeps everything cooler, longer.
- Reviewed in Canada on November 24, 2023Verified PurchaseI got these to eliminate condensation drips during the humid months, and works like a charm! Does an excellent job at maintaining drinks at a colder temperature longer too.

5.0 out of 5 stars If you want BRAGGING rights, or also mandatory for temperature BARRIER
Verified PurchaseIf you want bragging rights, these are the sets to get. If you MUST have the temperature barrier, these are also for you. Otherwise, they are not as practical as most glasses. I happen to love them. This review is for the 20-oz glasses, both in WAVE style and also straight style wall glasses (both). I will do reviews on all of the other, larger glasses as well, with pictures.
Shown is 1 Wave-glass wall, next to a straight glass wall, both are 20-oz, with 6 standard "crescent" ice cubes inside the wave-glass, and the other glass is empty. Perhaps you can JUST make out the waves in the glass that is holding the soda. Clearly this 20-oz size is too large for a 12-oz beverage, even with 6 ice cubes, and this is not the size for small beverages. I chose 12-oz of liquid on purpose. Note that the vacuum-chamber double-wall construction may require far less ice cubes depending on your situation. Many have said that the primary reason for choosing this style is the temperature barrier, without a doubt.
Both 20-oz styles are really wonderful to look at and feel great in the hand. The story behind the Borosilicate Glass, and the vacuum chamber between the panes makes this a great story while enjoying a beverage with someone. I have heard that ice-dispensers could crack the inner wall, but I filled 2 of the 20-oz glasses with my crescent-cubes dispenser from the fridge door (not small cubes), and had no issues. These are sturdy, and have a pleasant weight to them, but are still FINE glassware, not for children or clumsy people. I find them very sturdy, but still would not toss in a sink, nor stack in a full sink, and I would treat like a nice wine-glass.
Part of my job is serving occasional beverages in the office, and sometimes (fine dining) public restaurant dinner functions with my boss and small teams. I fully admit that the straight-wall version of the 20-oz glass does seem in many ways like a flower vase. Remarkably so. But if you want the large size, this will be your new go-to glass. I prefer the wave-wall version, no question, so does my fiancée. The wave-wall versions (only available in wave, in the 2 larger size glasses) feel much better in the hand - these glasses are just a bit larger than normal glasses in their size class of course. The waves make them easier to hold, even though I have XL hands. This whole set was a gift by the way (all 7 styles, 14 in total), and when my fiancée saw them, my son was at serious risk of NOT getting the glasses at all. Not kidding. I hope she still feels this strongly about me, as she was about these glasses.
Some said that the LIP is too sturdy, and may not be easy to drink from, I'm not sure what they mean. Fiancée is 5' 4", small hands, and was going to fight someone (me) to get the large version of this set, 20-oz. If you give these as a gift, do NOT let your fiancée/wife see them, or you will be buying more than what you planned for. And your original gift may be delayed until replacements come. I am not putting these in the dishwasher, and no idea how we could break these sturdy things, except for an accident of course. If one ever breaks, I will absolutely replace it.

5.0 out of 5 stars Beautiful insulated glass
Verified PurchaseThese are comfortable to drink out of; they are dishwasher safe; they keep drinks cold and are high quality. The glass doesn’t “sweat” and is comfortable to hold. The glass is clear & sturdy. They are stylish and elevated. I love that there is a 20 oz option. Excellent quality. Love them! Very good purchase!

5.0 out of 5 stars Past the Portion Police. They're back!
Verified PurchaseThese are very well made. They keep hot beverages hot or cold beverages cold much better than single-wall glasses. Water for tea can be microwaved to a boil in these glasses, and the outside is ok to handle. These are hefty, about like a typical pub beer glass. These stand straight without taper, so they don't tip over as easily as a typical pub beer glass. There is enough thickness for strength, so there is a little more heat transfer to the beverage than the thin and light (and fragile) double-wall coffee mugs.
Get these if you can.
The only problem with these is the Portion Police. The 20oz size became unavailable shortly after I got mine, just like when I got my 20oz double-wall coffee mugs. It seems all suppliers for these got shut down.
(four weeks later) Got two more when these became available again, Sun's Tea brand, same hefty glass. They have been used every day. Ice, hot, cold, microwave, dishwasher, no problem. My old favorite double-wall mugs are rarely used now.
(years later) These get a lot of use. They are a household favorite. They do NOT get any special care. They still shine, no chips or cracks. One of them broke due to my fumble, and my attempt to catch it increased the force of the impact. When it broke, there was no 'pop'. The broken shards stayed in the kitchen sink. I don't think the space between the walls is vacuum.

4.0 out of 5 stars Sturdy functional but lacking mouth feel
Verified PurchaseA long time ago, I had someone explain to me "mouth feel" concerning what kind of glass tea was best served. I balked at that at the time, but since learned it's actually real. To put it simply, for most beverages this thinner the glass that touches your lips, the better the taste experience. Look at high end wine glasses versus the cheap ones.
These glasses have all the attributes you want in an insulated glass - except mouth feel. I think other reviewers pointed out the same issue in different terms. Insulation, great. Sturdiness, great. Capacity, great. Overall quality, great. Price, yes a bit pricey but then you get what you pay for.
The only solution I can think of, is shown in the seller's photos. Use a straw. And choose a drink which is appropriate for using a straw.
Now if you don't care about the mouth feel thing at all, these glasses will suit you fine.
