Question: BPA free?  Does it say on package or anything?
Document: Good size for large mouth water bottle, ie, a KOR Delta BPA Free Hydration Vessel. Our regular size cubes were a little too big.Ordering another pack of these.
cubes, so I'd say I'm happy with the purchase.
It's an ice cube tray... nothing special to say. It's flexible enough to get the cubes out, and stable in the freezer. So no reason to downvote.
very good product and fast shipping. I would definitely suggest this products to friends and family. They are something the whole family can use,
useless. They warp. I suggest getting stainless steel or something harder than this. They warp and the water ends up spilling.
i was on a hunt for a medium sized ice to chomp on. i let them get melty and they were decent. not as perfect as the elusive ice tray i was after. if you're a chomper then these are way easier to chomp on that all standard sized ice trays. i have 4 trays and it's enough to fill up 2 large cups if you're wondering about the yield.
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!
You need to bring the water to them.Arrow: Very Good, very easy. Pouring off excess to level is fairly easy.Cubette: Very Good. very easy. Slightly easier to level than others because there is no lip.Camco: Very Good. Easy. Slightly more care needs to be taken to level, but easy enough (with good eyes and steady hands).-=-=-ReleaseProgressive: a misery.
You can always bend them opposite of the curve before filling them with water. That helps a great deal, although not completely. I understand that these are made for mini refrigerators, but if Camco would make some for regular-sized refrigerator-freezers...they would have a hit on their hands.You won't be disappointed with these trays.
Yes, these are small, but it is what I needed. They seem fine and will fit in an RV freezer with no problems.
Answer: I've been wondering the same thing, but unfortunately I don't remember seeing it on the  package either. I do believe that silicone is BPA free and I'm praying that I'm right!
