GOOFIT Diller Thermos - Double Wall Vacuum Insulated Coffee Thermos thermos cup for cold water Stainless Steel Travel Mug & Beverage Flask BPA Free Keeps Cold 24H Hot 24H 16 Oz Black

I purchased this thermos for use in a walker basket following surgery, and also to carry hot/cold drinks in the car. I have tested its heat-holding capacity for 3+ hours and coffee is still piping hot. The main thermos top screws on tightly. There is push-button release of the sipping top, which opens gently and doesn't drop down while drinking. There is also a lock to secure the thermos top to prevent leaking. I ordered the pink thermos and love the color. The only con I can think of is that the thermos bottle is fairly narrow, and you will have to tilt your head far back to be able to drink all the liquid.

I did not use this immediately after I got it as I was saving it for a gift but decided to check it out first when I lost my Zirushi...LOL! ...when I did it only lasted a couple weeks before it started leaking...I thot...( As you can see by the pics) But I thot that didn't make sense, the way it was made so checked it out a little better, and found out it was leaking at the seal at the TOP, because the seal was twisted and not inserted correctly! so beware customers! to put everything together CORRECTLY!! I LOVE everything else about it tho! It keeps hot just as long as my Zirushi (which I have had for many years and incidentally has seen a LOT of abuse...Even been dropped numerous times and hardly shows anything besides a bit of paint off...(as per 1st pic above) and which I've had for years without ANY ISSUES!

This is a great product. It has a second hole in the top to allow for the release of suction so the fluid flows easily - one of the only thermoses to have that feature. I have had a black one for about 2 years and it looks brand new. I wish they had a larger selection of colors. I'm not a fan of pink or red but would love to have a couple more different colors.

Buena calidad

Great little thermos, does not leak, and unlike the similar zojirushi, no PFAS/forever chemicals

We have tried this one so many different times and no matter what, water leaks out of the post where the lid clips into the cup. Like on the back side. Maybe it’s a seal issue with just this cup but regardless, my 6 year old won’t use it.

I like this double walled insulated water bottle that keeps water cold for long time. It fits in the cup holder in my old sports car. The problem is, it is a little too narrow and tall for my cup holder and the way the cup holder is designed, it rattles around in it and I fear it’ll fall over when I make turns, not a fault of product, just the way my car cup holder is designed.The only other thing is I wish it had a carrying loop, otherwise it’s a good water bottle, a little overpriced compared to similar products.

Keep hot stuff for a long time
