I found this bottle to be excellent quality! It is very attractive (the picture doesn’t do it justice) and would make a good gift. It is a heavier bottle – quite sturdy with a screw on cap and removable strainer which would allow you to use it as an infusion bottle or, if you’re a tea drinker as I am, to throw a tea bag in without it ending up in your mouth. I tested the two claims that the seller makes: That it will keep drinks cold 24-36 hours and that it keeps jot drinks hot for 12 hours as well as a complaint that I had seen in other reviews about the bottle leaking.
1. Does the bottle keep drinks cold for 24-36 hours? Yes, assuming that the drink contained ice when it was placed in the bottle. Plain cold water from the tap stayed discernibly cold about 5 hours which is still pretty impressive. When I filled the bottle with ice before adding the water, the was was still actually cold after 36 hours.
2. Does the bottle keep hot drinks hot for 12 hours? No. I placed boiling liquid in the bottle and 12 hours later it was just slightly lukewarm, no where near hot drink temperature. The bottle keeps hot drinks at a realistically hot drinking temperature for about 6-8 hours which, again, is pretty impressive but not the 12 hours claimed.
3. Does the bottle leak? No. As I was reading some of the other reviews, I noticed that some people complained about their bottle leaking. I filled mine with water, tightened the lid, and laid it at a 90% downward incline on a folded towel for three days. At the end of the three days, the towel was perfectly dry – my bottle shows no sign of leaking.
In my opinion, this is a solid 4 star product. I removed one star for it not living up to the sellers claim of keeping hot drinks hot for 12 hours.
