[This review was collected as part of a promotion.] These are great for warm beverages on the go! Upon initial use, they appear to be durable and leak-proof so far. The design is cute, and it’s a nice size.

These cups are advertised as "microwave safe" and they most definitely are not! I put the cup in the microwave, without the lid, for 20 seconds, and the cup came out melted and burnt on the bottom. Definitely not safe to microwave.

[This review was collected as part of a promotion.] Eco friendly cups. Great for coffee on the go. They are leak-proof and the insulation keeps your drinks hot or cold. The designs on the keep are great. Durability 10/10.

I prepared hot chocolate for family taking an early morning 3 hour drive to a wedding. It took 3 attempts to get ONE lid to fit properly without cracking.

[This review was collected as part of a promotion.] The designs are super cute and the grip feels great, but the lids leak if you’re on the move. Fine for light use—just don’t expect it to be spill-proof.

Please bring back 5 and 3 oz. cups ASAP. Love and have used the 5 oz cups for decades. Had to order another brand, don’t like them half as much. Also miss holiday paper plates.

When you first pour the coffee and put the lid on, everything is fine. But, buy the time I get to work there is a crack in the coffee cup lid! I haven't been bugged too bad, I figured maybe it was a defective batch

[This review was collected as part of a promotion.] These cups are really convenient for morning coffee, I like that they come with lids as well. They provide good heat insulation and seem to be fairly leak proof from what I can tell.

They leak at bottom seam after putting in hot liquid. Every time you set the cup down, the bottom gets soft and your liquid starts going thru the bottom. It will last for a single use, no refills. Also if it sets 2 - 3 hrs it will leak out.

A co-worker was heating water in the microwave in his cup and we smelled something burning. When he took his cup out of the microwave he saw that the bottom of the cup was smoldering.
