Necomi500ml Smart Thermos Cup, LED Temperature Display Water Bottle, Stainless Steel Vacuum Travel Mug for 24 Hours, Hot and Cold Tea Coffee Vacuum Thermoses Cup for School, Home, Office

Very nice thermos. I bought 2nd pcs now. Keeps hot water up to 3~5 hours depending how hot was yr coffee or tea. And led touch screen works perfectly and helps u to control the temperature. I recommend this product without any hesitations.

Terrible product, feels very very cheap and does not display temperature

Its good and keeps the water cold for long times

ممتاز جداً

Does not keep hot. Bad insulation

This thermos does a great job keeping drinks hot or cold for hours.The LED temp display is a nice touch—helps avoid accidental sips of burning hot tea.It’s sleek, leak-proof, and fits easily in my bag.Perfect for school, office, or travel

I bought 2 of these.At first, I was impressed with how this product feels and the fact that there is a mechanism to prevent ice from falling off while drinking.But there are serious problems with it:1. After putting it in the fridge for a couple of days, the metal ring around the cover fill off on both bottles when trying to open them.2. When the metal ring fill off, the plastic display on top that is showing the temperature was easily removed and I can clearly see that there is a battery inside. I thought the seller said it does not need recharging!! I don't think this battery is rechargeable.3. I washed the bottles with soap thoroughly, but still there is a strange odor coming from them while drinking.I took pictures of it, but Amazon is not allowing me to upload pictures.I will return this item and look for something else.

Good to hold hot.
