The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Ovalware RJ3 is the rare pick that earns a specific nod from a high-trust tester: seriouseats.com singled out its "sleek glass body, which is reminiscent of a laboratory beaker." That design language carries through the rest of the coverage, with verified-purchase reviewers and r/coldbrew members highlighting the airtight hard-plastic lid that keeps fridge odors out and a simple, easy-to-clean construction. Manufacturer and retailer listings claim the airtight seal keeps brew fresh up to two weeks, and community members corroborate keeping a batch for roughly five days to two weeks without noticeable degradation.
What reviewers liked
- Endorsed by name in a high-trust roundup (seriouseats.com) for its glass-beaker design
- Airtight lid praised by r/coldbrew members for blocking fridge odors and extending freshness
- Large verified-purchase base (~13,510 ratings at 4.5) and easy-to-clean removable stainless filter
Where it falls short
- Multiple r/coldbrew users report the borosilicate glass is fragile, with some breaking two units without abuse
- One community comparison calls its filter 'worse' than competing metal filters
- At ~$33 it is among the pricier glass pitchers here, and the 34oz capacity is modest for heavy drinkers

I make my cold brew at home using this cold brew maker. I love the hard plastic, airtight lid to keep out fridge odors, and simple design. I ...
I have tried an 8:1 and 10:1 or so, and the water doesn't cover I'd say the top 25-35% of coffee, except when I'm putting it in for the first time.
