What it is

The trays are fully flexible silicone moulds with long narrow channels instead of square cube wells, sold three to a pack with a silicone lid for each. The stick shape is sized to pass through the mouth of a sports bottle.

Each tray holds slightly more than one cup of liquid, which one reviewer measured while freezing lemon juice. Three trays is enough to keep a household supplied without refilling constantly.

How it works

Full flexibility is both the feature and the handling problem. Because the entire tray bends, the sticks release whole rather than breaking into chips, which is the failure of trays built on a rigid frame. The same flexibility means a filled tray sags, so reviewers carry the trays to the freezer on a baking sheet and leave them there until frozen.

Underfilling is the technique for bottle use. One reviewer fills each channel slightly below the top so the finished stick is narrow enough to drop into a bottle without catching.

The lid does two jobs. It seals well enough that reviewers report no spilling on the way to the freezer, and it lets the trays stack.

What reviewers report

AddToPick read ten US five-star reviews of these trays, coming to roughly 3,800 characters. The reviews are short, and bottle fit is the subject that repeats.

Named limitations from these five-star reviewers:

• The sticks fit narrow bottle openings. Reviewers name specific bottles they use, and one reviewer measured a target opening with calipers before buying.
• Release is clean. One reviewer contrasts these with a rigid framed tray that always produced chips, and reports the sticks coming out whole every time.
• The lid does not leak. Reviewers report carrying filled trays without spilling, and one attributes the seal to the lid being silicone.
• The trays are used for more than water. One reviewer froze two cups of lemon juice across two trays and reports no longer wasting lemons.
• Reviewers describe the silicone as supple enough to avoid the cracking that plastic trays develop. Named limitations from these five-star reviewers:
• The tray needs support underneath once filled. Two reviewers describe carrying the trays on a baking sheet to the freezer.
• Slight underfilling is needed for the sticks to drop into a bottle cleanly.
• Fit depends on the bottle. One reviewer advises measuring the target opening rather than assuming, and notes other stick sizes exist.

Who it is not for

• Anyone who wants standard cubes. These are long sticks for narrow openings, and a stick is the wrong shape for a tumbler of spirits.
• Anyone who will carry a filled tray by hand. The tray is fully flexible and sags when full, so a baking sheet is part of the routine.
• Anyone with an unusual bottle opening. One reviewer measured before buying, and advises others to do the same rather than assume the fit.
• Anyone who wants to fill trays to the brim. Filling to the top makes a stick that catches on the way into a bottle.

Questions people ask

Will the sticks fit my water bottle?

Reviewers report the sticks fitting narrow sports bottle openings and name specific bottles. One reviewer measured the opening with calipers first and advises others to check rather than assume.

Do the ice sticks come out whole?

Yes. The whole tray bends, so the sticks release intact. One reviewer contrasts this with a rigid framed tray that produced chips every time.

Does the lid leak on the way to the freezer?

Reviewers report the silicone lid sealing well enough to carry a filled tray without spilling, and the lids also allow stacking.

How do you carry a floppy silicone tray?

Two reviewers put the filled trays on a baking sheet, carry the sheet to the freezer, and leave the trays on it until frozen.

Can the trays freeze anything besides water?

One reviewer froze lemon juice, fitting slightly over one cup per tray, and reports no longer wasting lemons that would otherwise spoil.
