this stuff works great . with the orange cubes 3 dozen crickets lasted 4 days maybe 5, with this stuff 9 days .i am not sure if the geckos eat less or  this just keeps the crickets alive longer but this with the blue stuff works .

Remembered this from the 'old days' and it works great, doesn't take much hand pressure to crush the ice. Works better than the electric ones!! Just one cube at a time, the only problem.

awesome! and entertaining there is a huge difference in how much easier and smooth it is to work with this cube versus the original rubick's cube.

These make excellent ice cubes! I do wish they were ever-so-slightly more stable when filled with water, but I've learned to carry them on top of my palm with fingers outspread, from sink to freezer.

To get the cubes out, just push up from the bottom. You can't crack the tray like you would with a plastic one. Best part: the cubes are, well, cubes! They're an inch on every side, rather than the bathtub shape of regular ice cubes! They look awesome in a drink!

Oh, and if you experience the white flaking people are so freakishly paranoid about, it's just calcium sulfate from your tap water. Soak it off in a vinegar-and-water solution for 20 minutes, rinse well, and make your ice cubes with bottled water instead.

We've been through so many ice cube trays in the past two years we finally decided to upgrade to long-lasting silicone. Hopefully, these won't crack and leak after a few months of use!

They work very well. The thing is, I have discovered (again) that I pretty much never use ice cubes, no matter how they are made. But these make nice ice cubes and they don't disappear to nothing when left in the freezer for weeks. A good solution to the ice cube issue.

Originally bought this for my boyfriend, because he was commenting on the big cubes some fancy bars use and how they're better with all the slower melting and what not (that has all been touched on here). He then went and bought more himself to give to friends (but I think ended up keeping a few extra trays himself). So I had to buy one for my house, and will probably buy another since they only make six. HOWEVER, if you plan ahead when there's a party, it's easy to just pop them out once they're frozen and put them in a ziploc, then just refill the tray again (this would also help for the people who have issues with freezer odors getting into their ice when it sits for awhile). I really don't have a huge problem with spilling them. I do make a point of not filling them ALL the way to the top, simply because water expands when freezes so no need to be perfectly filled to begin with. Also don't have an issue getting them out, I sorta just push the cube up from underneath while pulling down on the silicone. It's a flexible and slightly stretchable material, so while the cubes don't pop out like with conventional plastic trays, it doesn't take rocket science or bodybuilder brawn to remove them either.

They trays work great little effort to get the cubes out. The last different set I had you had to crank and bang on them to get them out. These they just pop right out easy.

This was great! My tried to convince me that he solved his rubic cube but I can clearly see some of the stickers have been moved.  So I got him this cube to practice on. The two best features, no stickers and it moves a lot smoother than the typical cube making it much faster to use.

I got my first cube just a couple weeks ago. I loved solving it, but was annoyed at it getting stuck and keeping me from pulling off my awesome moves (ok, I'm a beginner and only know simple moves, but it was getting stuck). I found this speed cube and got it, and it seems nice. I can easily solve the cube using the beginner's method and it doesn't get stuck, nor has it "popped" or "flipped" on me. Overall, quite a nice way to occupy my hands while relaxing.

My only complaint is the colors are eye searing. Red, blue, and white are fine, but the orange, green, and yellow are neon. And the orange is so overpowering, I can't always tell if I'm looking at eye-blinding orange or red. I'm sure you can buy different stickers or something, but out of the box, you might want to wear sunglasses. Or learn to solve it blindfolded.

I ordered these trays because I wanted to have large cubes for my drinks. The cubes take longer to set (about 3 hours), compared to my regular ice tray (which will be set in 1.5 or 2 hours), but they do last much longer as well.
I've used the tray to freeze small portions of food (cubed fruit, pulled pork, cooked spinach) which are perfect size for a lunch during a busy week day.
Also I placed the tray in the oven to prepare flan, and they turned out really cute.

The size and action of the cube is great, just wish the red and orange had a bit more contrast, not easy for me to distinguish between the two in some light conditionsgreat experience getting them so quickly with Amazon prime! Thank you!

I recently moved into a new town house with a  refrigerator that did not have an ice maker.  I had to come up with a solution to have ice cubes on hand.  I tried a few different things and I was surprised to find that these tried and true ice cube trays were the best way to go.

After using a few store bought models made of silicone or some type of flimsy rubber and having trouble with the ice cubes coming out easily.  I remembered using these types of plastic trays when I was a kid back in my parent's home many years ago.  I looked around a bit to see if something similar existed and sure enough, Amazon had them.  I ordered them without hesitation, hoping that they worked as smoothly and easily as I had remembered.

I filled them up with filtered water and stacked them in the freezer.  You can stack these trays very easily as they are designed for that which is nice.  When it came time to get the cubes out of the tray, it was a simple twist with barely any force and then dump into the plastic bin that I also ordered.  This was as easy as I remembered it, and far easier than many of the newer ice cube trays that I bought at the local retail store where I sometimes had to pry the cubes out.  I was dumbfounded that the easiest ice cube method was the old school version.  I'm not sure how they've managed to regress so much in ice cube technology over the years to be honest.  Something that simple shouldn't be hard I would figure.

Bottom line, if you don't have an ice cube maker in your fridge, get these trays and save yourself frustration and mess over the other ones.  These worked 40 years ago and they still work flawlessly today.  They're old school, but sometimes that's just better.

Highest Recommendation.

These work great!  Perfect size cubes. Extraction is very easy. Highly recommend.

Works great, love having large ice cubes.  Emptying is a bit difficult.  After a few busted knuckles, discovered that running hot water over the bottom side of the trays makes emptying a lot easier.

Excellent cube not only for those learning to solve the 2X2 cube but also those looking to improve their speed. Very smooth movements and all the pieces stretch a little so allow movement even if the sides are not perfectly aligned . My 8-year old son directly compared his speed with this cube with a friend's non-stretchable cube and finds his speed to be nearly 50% faster with the Cuby version.

This is a great little set for making big cubes for whatever the heck you want your big cubes for. Cocktails will be the primary use for me. For that, they do the trick. But, there are 2 minor aspects of usage that made me go with 4 instead of 5 stars:
- the filling holes on the spherical tray are too small to use without a funnel. I wind up filling the entire upper chamber around the spheres with water, which makes ice I don't need and can make a mess (which defeats the purpose of having the holes in the first place). Small thing, but still not ideal.
- the fact you can stack the spheres on the cubes at first seemed like a really clever design feature that allows one to first fill up the cube, then stack the sphere tray on top - which acts as a lid and allows easier transfer to the freezer. I still like this feature but because I like the make my cubes as large as possible, I fill the cube tray to the top with water. Naturally, then, once it freezes the sphere/lid gets stuck to the bottom and is difficult to remove.

Both are by no means deal breakers, but they do limit usage and are worthwhile to know about IMHO. Full disclosure: I got to buy this at a discounted price on the condition I leave an honest review.

I like these - easy to pop the cubes out and they stack very nicely (you do not have to keep up with the direction since they are not designed like the cheap ones!)  This is the 2nd order I received as I can no longer stand the cheap ones and tossed them in the trash - all I have now are 2 sets of these Rubbermaid ones and very happy!
