Yes, they are, as the Product Description states. They are dishwasher and microwave safe.

No. It's not stated anywhere that they're microwave-safe, so I would definitely not try it.

They do not say either on the cups or the package whether or not they are microwave safe. We have microwaved them a few times without incident, but I try not to do it often.

I don't know what the manufacturer has to say about the matter, but I would not put them in the microwave. I have been putting mine in the dishwasher, and I think that was a mistake. I have broken two of them because the glass seemed to be very fragile. Make no mistake, even though I don't recommend the microwave or dishwasher, they are a great buy. The double glass keeps the coffee warm for longer than regular coffee mugs!! I was so sad when mine broke. I will say, it was the gentlest bump that broke them...even so, I will be replacing them soon. I love these glasses.

Yes! Microwave safe..... But do be very careful when washing... If the glass slips off your hand.... Say good bye!

Yes they are, they are dishwasher safe. I have made hot chocolate and boiled the water over when I microwaved it. Don't put hot and then cold in it, it will crack.

No, they are not microwave safe! Plate broke in two after microwaving under 3 minutes.

No they are not microwave safe and they are not labeled microwave safe. In general heating plastic releases carcinogens. Microwaving with a glass pyrex measuring cup and pouring in the contents does the job well.

No! You will ruin your mug! Do not put it in the microwave or the dishwasher.

Yes you can put them in the microwave. Only caution from me is they are NOT 18 oz mugs, they are 24 oz! They are huge!

Although I have not used them in the microwave, I believe they are safe for microwave use.

Good question. I wouldn't use them in the microwave as I don't with any plastics. So, my vote is no.

They are microwave & dishwasher safe. Probably not safe in a conventional oven, though.

I have not used in microwave and would not. I was always taught no metal in microwave, this mug is very much metal. Heat your drink and transfer to the mug it will keep it hot

Yes, but I recommend heating the water inside the mug. I've cracked several by pouring very hot water in them or by washing with cool water when still very warm. I never had one break when heating water in a microwave oven, even to the boiling point (by accident).

I have used them in the microwave and had no problem, but i've only done that once ar maybe twice,,, the glass is relatively thick as well, there is a big seam down the side of the glass, opposite the handle, but we didn't think this was a big deal, they are nice mugs, 17 oz is to the very top of the rim....btw, I use them for coffee, tea, hot chocolate

Yes they are microwave safe. I've used them a number of times there and they stay fairly cool to the touch unless you nuke the food for over six minutes. This was my second set of this style and have had the first set over ten years.
