Review on Stainless Leakproof Portable Traveling Multicolor by Dana Mahendra

I ordered these for future gifts and to compare with these much cheaper 8oz bottles. These have a good build quality and have been tested. Tests: fill 2/3 with water, put upside down for a few hours, check for leaks; try repeating the water, but set it to a few hours. There were no leaks, the water tasted good. The build quality is good, the finish is good. Good bottles throughout. Compared to others, these contain 50% more liquid, but cost more than three times the price per unit. The build quality is about the same. These bottles are 7" tall, the rest are 5.4". That 1.5 inch difference really seems like a lot when you hold them side by side. These pistons are made from 304 stainless steel, which is fine as that material is ubiquitous in such applications. The other bottles are also likely 304 stainless steel, but they don't mention what steel is used.
