HYDY Double Wall Insulated Tumbler 18/8 (304) stainless steel food-grade, BPA free Multiple sizes & colors (White Marble-Eucalyptus)

First, it's important for me to have a single cup that I can use for both my morning coffee and beverages later in the day. When I first opened my HYDY cup, I noticed there was no toxic smell from the plastic and materials. I used it for my morning coffee and it kept my coffee warm until I had finished the entire cup which normally takes me 90 minutes to a couple of hours.Next, I live in Miami and Las Vegas. It's equally important to keep beverages cold in both places. If there's one thing I hate it's taking a drink to the beach and it being melted on my walk there or shortly after. HYDY kept my drink cold then entire time! So cold that I will be ordering a larger cup to use as a pitcher!Thanks for making awesome products HYDY!

This tumbler came out to be a bit smaller than I expected however I bought this as gift and it definitely scored style point.I don't think the insulation is great. I've tested both hot & cold beverage in the tumbler and neither lasted long enough for me. I think it may be because of the wide-mouth design of the tumbler.

The giant gaping hole in the lid makes this pretty useless as a travel mug. One slight tip to the side and your drink is all over the place. The hole also makes the vacuum insulation a lot less useful since your drink is constantly exposed at the top for heat/chill to escape. Do not buy this unless your "travel" consists only of gentle strolls down the sidewalk or the calmest of car rides with zero potholes .Otherwise very stylish and fairly easy to clean, aside from having to wrestle a bit with the silicone base. Materials are high quality.

I love the look and feel of this product. However, the lid is not very practical. It has an opening so it does not hold heat for too long. I decided to keep anyways because it does not take me too long to finish an 8oz drink.

This tumbler is so visually stunning, even the packaging is perfection. It does a great job of keeping conserving the coolness/heat of my drink longer than expected. The vacuum seal lid does what it is intended to do. Only wish was that the sippy part of the lid had a lock mechanism to block off the top when on the go. Otherwise, highly recommend!

The marble print is not as exquisite as I thought, a little bit disappointed, I think the rose gold metal bottle is better.And there’s a hole on the lid for drinking so it can’t be sealed completely, don’t know how to bring it out.

I love this product! It’s easy to carry, and keeps my drink cold at all times, specially now in the warm summer in Southern California. It’s also great for hot drinks, like coffee and tea. It keeps the drinks hot for about 3 hours. Besides, it looks so cute :) I recommend it!!

Nice design, keeps drinks cold or hot without heat transferred to your hand but I got a slightly metallic taste with wine.
