What reviewers say
PlanetGoods Square Glass Food Storage 6-Piece Set
Buyers rate it 4.8 out of 5 from 10 ratings and call it sturdy, easy to clean and good for cutting plastic use. The main complaint is the lids, which take effort to seal properly.
Pros
- Well made and sturdy
- Stacks and nests well, especially with multiple sets
- All glass including lids, no plastic
- Easy to use and clean
Cons
- Lid is difficult to seal tightly
- Pressing two corners can loosen the others
- Six-piece label feels misleading since lids are counted
OXO Good Grips Smart Seal Glass Container Set
Reviewers praise the sturdy glass and tight-sealing lids and find the range of sizes useful for small lunches and larger meals. Some report inconsistent seals, and one notes the glass lip chipping over time.
Pros
Questions and answers
- Which set is better for meal prep?
- The OXO set, for its four portion sizes and oven safety to 550°F. The PlanetGoods set works for larger leftovers but gives you only one container size.
- Which has the better seal?
- OXO's four locking tabs with a removable gasket are the more reliable design. PlanetGoods buyers report the press-on lids are hard to seat and corners pop loose.
- Is the PlanetGoods set really six pieces?
- No. It is three containers plus three lids. Buyers call the six-piece label misleading.
- Can I put either one in the oven?
- The OXO glass is rated ovensafe to 550°F. PlanetGoods lists freezer, microwave and dishwasher use but no oven rating.
- Which lasts longer?
- Both use borosilicate glass. OXO buyers report chipped lips over time and shattering on tile; PlanetGoods buyers call it sturdy, but it has only 10 ratings so far.
- Is the OXO set worth the extra cost?
- No OXO price was given, so compare it at checkout. You pay for more sizes, a stronger latch seal and oven use; PlanetGoods gives you all-glass lids for $34.97 as of November 1, 2026.
