Question: how large are the ice cubes?
Document: These cube trays make the perfect sized ice cubes! They can fit in bottle openings which can handle 1&#34; wide so you can use them to add to bottled drinks. I think they work wonderfully in my Nutri Bullet when I make protein smoothies. Also, they freeze very quickly because of the size of the ice balls but are large enough that they don't melt too quickly like the tiny square ones do. Just be aware that they are NOT stackable!
These are great, come out so easy and just a nice size especially if you like to nibble on your cubes and don't have an ice crusher. Thank you!
Easy to use & clean up. The ice cubes actually comes out without any issues. No complaints at all. Definitely recommend.
These are great in the way that they just pop out from the bottom because of the silicone button. If you like small ice cubes that you like to crunch on, get these!
This product was purchased to use with children who have special needs. Great product for school or everyday use of making ice cubes.
I wasn't pleased with the way these ice trays worked. once the ice cubes were made I wasn't able to just push them out as it shows on the picture.
These i found to be quite nice, but I don't just use them for ice cubes. They work for candies and confections, and oils such as coconut oil. The shipping was fast.
The force you have to put into pushing on the bottom makes the cubes SHOOT out very fast.Makes cute little ice cubes, but definitely not worth the trouble!
Ice sticks to the inside, making it nearly impossible to get any cubes out. Lasted about two weeks and then the plastic started cracking. What a waste of $3.
The ice cubes are very difficult to remove from the chambers and the trays themselves are very brittle. One broke after the first freezing. The ice cubes they make are great shape but would noy buy again.
Answer: Small. These are a cute idea but not at all functional
