Question: what is the size of each ice cube?
Document: I bought these because of the small cube size which are perfect for ice buckets. The cubes release easily but the trays do loose their shape and won't lie flat in the freezer anymore.
Not just for RV's! My small apartment has a dorm sized refrigerator. A regular ice cube tray won't fit in it, but these do. The ice cubes are smaller, about 1/2 standard size, but way, WAY better than no ice cubes.
Compared to other ice cube trays, the cubes release from the tray very quick and super easy!You can imagine this saves a lot of time if you use the tray daily!Another big plus: the ice cubes are perfect size for not torturing my blender :-)
I bought these trays to make smaller cubes for smoothies (tho it turns out my great new small blender can actually handle the big ones, darn!). They're fine--a tiny bit flimsy, but not debilitatingly so... and they could be a little bigger overall--they're sorta measly, I wish they were the same size as regular ice cube trays so I didn't have to fill them so often.
Just ordered my second set of Camco Mini Ice Cube Trays. They make a smaller size cube which I really like in my drinks. Tried the Cubettes and nearly broke hands trying to get cubes out of trays. Finally gave up and dumped in sink to melt. Ordered the Camco and happy, happy. Cubes pop right out so easily and freeze quickly to replenish supply. Highly recommended.
I don't know why I'm so picky but, I like small ice cubes in my cold drinks. The trays don't make tiny ice cubes but, they are 1/3 - 1/2 the size of what I consider a standard ice cube. The tray is very flexible which is a help when a cube or two gets stuck.My one complaint about the product is that one of the trays I received (there are 2 in a pack), does not sit flat.
I came across these trays recently. Thought I'd give them a shot. They worked perfectly! The cubes pop right out of the tray with no muss, fuss or mess. I am sooooo happy with them. I am actually replacing my regular-size ice cube trays with as many of these that can fit in the ice making area of my freezer.As someone stated earlier, these trays do come with a curve in them and the stacking could be better.
are the PERFECT thingto make any drink cool quickly! These handy, inexpensive little ice-cube trays produce small size cubes which do just that!Rich people usually want, WHAT they want, WHEN they want it! Thesecubettes QUICKLY freeze, and QUICKLY cool drinks. Rich people also tend to have bigger refrigerators than those who are middle-class or poor...but everyone can use more freezer space! So -- these ice cubetrays ae just right for EVERYONE!
I admit it....I chew ice....I bought these after getting annoyed with the bigger size ice cube trays and how hard they were to bite. I searched add after reading various reviews on different ice cube trays I picked these.I received these in the mail in about two days from shipping. They make perfect size to chew right out of the tray. You do have to sort of put the tray side ways after you twist the tray to pop them out.
While the trays are small, they also contain 21 small cubes. It is a 2-pack. Yes, they would fit in an RV or dorm refrigerator, but I just like the small cube size for my personal water bottle. They stack well without dipping into the lower trays, and because they are smaller, they seem to freeze quicker. The trays have enough flex to them to make emptying them a breeze.
Answer: I'm not home to measure exactly but it's approximately 3/4" x 3/4" at the widest points. (Each cube tapers at the bottom)
