Smart Bluetooth Water Cup 600ML with Temperature Display and Tuya APP Compatibility

These tell you the temperature of the product but if you fill it with ice and cold water from refrigerator it will only start cold 4 hours tops indoors out of sun 2 hours in sun

I bought two sets of theses. So me and my kiddos could have one and I could give the rest to my team mates. Well only enough worked for me and my son and 2 team mates. Then after using it for a few days I notice the display doesn’t even change it just stays at 22 Celsius. After I discover this the quality just it’s worth the money. It does not leak so that’s a plus, they are not dishwasher safe so these need to be hand washed that’s not a big deal to me.

I got these on sale. The digital thermometer on the lid was unnecessary, but I was looking for a thermos use for them, and that part is great. The lid fell apart after the thermos was frozen (purposely done for its use), so that's the only problem with them thus far. Don't freeze it or drop it and that feature should be fine.Good value for the price and my use of them.

De las 8 botellas. 2 llegaron con la batería agotada. Y reemplazar las baterías es muy complicado.

I bought 104 of this product but 5 were not good. I will give 5 stars if I can have those 5 replace. The product is good and suit my needs

Bought as thank you gifts. The variety of colors was great. Each recipient was impressed

Despite not being able to view in Fahrenheit, put ice and water in, said it was 22 Celsius…. 36 hours later sitting out at room temperature … yep, still 22 Celsius! Opened, ice had melted and water was warm (room temperature)

Hermosos colores. Y muy herméticos no dejan salir nada. Y tienen exelente agarre.

Son buenos para regalos

What the same thing ,but needs to read in Fahrenheit with same price
