Well-built insulated bottle with accurate capacity and strong value
This is a solidly executed 25 oz insulated stainless bottle that delivers exactly what it claims at a very competitive price. The brand is not known to me, but construction quality is genuinely good.The interior is stamped SUS 304, which is essentially synonymous with the advertised 18/8 food-grade stainless. Machining at the lip is clean with no sharp edges or cosmetic defects, and the powder coat finish is even and durable feeling.Capacity checks out. Based on internal measurements, the main chamber is about 75 mm internal diameter with a 150 mm cylinder plus roughly 40 mm in the neck. That calculates to roughly 750 mL, which closely matches a true 25 fl oz rating. This is not an undersized bottle. The internal cavity widens below the mouth, so ice loading and cleaning are easy even though the drinking opening itself is narrower at about 53 mm.The double-wall construction provides a real thermal barrier. Outer diameter is about 89 mm, which implies a healthy vacuum gap between the inner and outer walls. In informal testing, it meets the advertised 12 hour hot and 24 hour cold performance. It is not a miracle performer, but it is solidly good and behaves like a properly built vacuum bottle should.The lid prioritizes sealing rather than quick sipping. You unscrew to drink. The gasket and thread engagement are excellent and it has been completely leakproof in a bag. This makes it a good choice for commuting, travel, and tossing into a backpack without worry.Overall size is reasonable for daily use at about 225 mm tall including the lid. For cup holders, it's best to measure yours first, as this is perhaps a bit wide. However, it should be fine for most backpack pockets.At $16.99, this is very competitive. You are getting real vacuum insulation, verified food-grade stainless, accurate capacity, and reliable sealing without paying brand premium. Easy 5 stars for delivering both performance and value.
