Rubbermaid Brilliance Review: A Truly Leakproof Plastic Set

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

Soup in a work bag is the test most plastic containers eventually fail. Rubbermaid’s Brilliance line is the plastic set independent kitchen testers keep recommending, and the reason is simple: its lids hold liquid in. This listing is the medium size on its own, five 3.2-cup rectangles with five latching lids, each roughly one person’s lunch. It is sold on Amazon.

The containers use Tritan, which is BPA-free and nearly as clear as glass, so you can see what’s inside without opening the lid. Each lid presses onto a thick silicone gasket and locks with two side latches, and vents built into the lid let steam out so you can microwave with it on. The lids also fit Rubbermaid’s Brilliance Glass containers, so one lid style can serve a mixed plastic-and-glass cupboard.

Key Specifications

Rubbermaid Brilliance Seal and Leak Performance

This is the reason to buy it, and the three independent tests we found agree. Testers filled Brilliance containers with water and shook them hard, and not a drop got out; Prudent Reviews also held sealed containers under water and saw no bubbles and no water getting in. America’s Test Kitchen, which named Brilliance’s 10-piece mixed set its favorite plastic option, went further with that set: it dropped filled containers and froze them before repeating its leak test, to see whether the seals wore down over the course of testing.

Why it seals: Your Best Digs found the Brilliance gasket about twice as thick as those on the other finalists in its 2023 test of the 14-piece set, thick enough that the lid floats on the rim until you press it down and lock the latches. Owner feedback is strongly positive, and most of the praise is about exactly this: lids that stay sealed, containers that stay clear, and food going from freezer to microwave in the same box.

Stains, Odors and Freezer Use

Rubbermaid lists the containers as stain- and odor-resistant, and tomato sauce, the usual culprit, mostly bears that out. Prudent Reviews saw no visible discoloration after its tomato sauce test, though a slight garlic smell lingered after washing. Your Best Digs ran a harsher version, freezing marinara in the containers and microwaving it until it boiled, and found a faint rosy tint along the beveled edges, much lighter than on the other plastic containers it tested.

Freezer and dishwasher: in Prudent Reviews’ freeze test the lid corners bulged slightly while the areas around the latches stayed firm, and the lids returned to shape once thawed. Your Best Digs put the set through a heavy-duty dishwasher cycle and it was the only plastic container in that test to come out with no pitting or scratching. The recurring complaint in owner feedback is the lids: a minority of owners report lids cracking across the middle over time.

Latches, Gasket and Cleaning

Here the testers split. America’s Test Kitchen found the latches effortless to open and close. Prudent Reviews found the opposite: closing took a firm push and opening took some prying, because the seal grips hard and the latch flaps are thin and stiff compared with other sets. If you open containers many times a day, this is the detail to weigh.

The gasket is permanently attached. America’s Test Kitchen counts that as a plus, since there is no loose part to lose and the silicone is soft enough to clean around with a sponge. Other testers see a hygiene trade-off. Prudent Reviews found sauce trapped behind the fixed gasket hard to reach; Your Best Digs could bend the gasket to scrub underneath it, but suggests soaking the whole lid in a cleaning solution to fully avoid lingering odors. If you want a seal you can pull out and scrub, look at a removable-gasket design instead.

Microwave, Dishwasher and the Plastic Question

Rubbermaid rates the containers safe for the dishwasher, microwave and freezer, and the vents sit under the latch flaps, so you flip the latches up to reheat with the lid in place. The plastic version is not oven-safe; for baking or reheating in the oven, the glass version is.

America’s Test Kitchen goes further than the label. It advises against microwaving food in any plastic container, washing plastic containers in the dishwasher, or filling them with hot food, citing growing concern about micro- and nanoplastics released when plastic is heated, and it recommends hand washing instead. That is caution about plastic in general, not a finding about this set. If it matters to you, the workaround is cheap: Brilliance Glass bases take the same lids, so you can store and carry in plastic and reheat in glass.

How Does It Stack Up Against the Competition?

The plastic Brilliance set sits below the glass options on price and above basic press-on plastic tubs. These are the alternatives testers compared it with most often.

Is the Rubbermaid Brilliance Worth It?

Buy it if your containers travel: lunches in a backpack or work bag, leftovers stacked in a crowded fridge, soup you would never trust to a press-on lid. The 3.2-cup size is a lunch-for-one container, and a five-pack of one size is the simpler buy for weekly meal prep than a mixed set full of sizes you rarely use. Plastic also keeps a full bag lighter than glass would.

Look elsewhere if you reheat in your containers every day or want them in the oven: the Brilliance Glass 3.2-cup set costs a little more for one fewer container, is oven-safe and takes the same lids. If a gasket you can pull out and scrub matters most, OXO’s Smart Seal glass set has one, though America’s Test Kitchen found its latches stiff and its lids holding on to fishy smells, while Prudent Reviews found the latches easy to open and close. For dry pantry goods or cheap freezer overflow, Rubbermaid’s EasyFindLids cost much less per container, but their snap-on lids have no latches and testers split on them: Prudent Reviews saw drips in its shake test, while Your Best Digs found its vented-lid version leakproof but badly stained and pitted after the dishwasher.
