☕ Stanley Master Series: Unbreakable Packable Mug, 18oz Stainless Steel - Hot 12 Hours, Cold 16 Hours Review

I like the mug but it makes a very loud noise when I open it with hot coffee in it. This might be an issue on my 1st MTG of the day.

Update. Yes, I was initially satisfied until the bottle started to heat up. It's no longer isolating and I don't understand why. It's not even half a year ago.

Stanley bottles are well made and come with a lifetime guarantee, but I don't like the metal rim on top of this bottle because it loses heat and is always hot. I also have problems closing the lid, there is some defect, I always have to try 3-4 times to get the lid on the edge of the bottle.

I love coffee too much not to drink it 24/7. I carry this thermos filled to the brim with coffee everywhere. Stanley has endless options for insulated drinking vessels, with the most popular being ones with a detachable cup that attaches to the top. However, this one is much simpler. and smooth appearance. Much easier to pack in a backpack or drink holder. Looks great. Extremely durable. Yeti and RTIC offer similar thermos flasks. However, only Stanley looks like "Stanley's Green Thermos". As…
