The YETI Rambler 20 oz Tumbler is pretty durable, especially when it comes to keeping your drinks hot or cold for a long time. Its double-wall vacuum insulation does a great job with temperature control. Just a heads up though—while it's strong in many aspects, it's not completely leak-proof.

The tumbler has a MagSlider lid, which uses magnets to help reduce spills, and this is really handy when you're on the move or driving since it fits well in most car cup holders.

But, even with the MagSlider lid, it's important to keep the tumbler upright because tipping it can lead to leaks. That's something our research pointed out a lot.

This thing's made from stainless steel, so it's quite sturdy, and as a plus, you can toss it in the dishwasher. A lot of reviews mention its durability and how easy it is to clean, which is why people use it daily.

If you're thinking about carrying it in a bag or in situations where it might tip over, just be cautious since it isn't fully leak-proof. If having a totally leak-proof tumbler is crucial, you might want to look into models with screw-on lids.

Overall, the YETI Rambler is a solid choice if you want to keep your drinks at the right temperature. Just try to keep it upright to avoid any spills.

Whether at home, at work, or while traveling, its insulation and build make it a great everyday option if you're okay with the lid situation.

The YETI Rambler 20 oz Tumbler is pretty reliable for keeping your drinks hot or cold for longer, thanks to its double-wall vacuum insulation. That's how the manufacturer describes it, and it seems to hold up based on what we've found.

A lot of folks have mentioned their coffee stays warm for hours, often around four hours or so. This kind of performance is a big reason why people like using it throughout their day. Even professional reviews have backed up its ability to hold temperatures well.

Now, about the lid—it's not completely leakproof. Our research shows there can be some small leaks, especially if the tumbler isn't upright.

So, while it's awesome for temperature retention, just be careful if you're planning to toss it in a bag.

Overall, if you want something to keep your drink at just the right temperature, the YETI Rambler is a solid choice. Just a heads-up: it might spill a bit if it's tipped over.
