Tea Water Separation Cup Travel Mug Stainless Steel Vacuum Insulated Water Bottle Tea Cups for Men Portable Tea Thermos 600ml

this product is not just bad. it's hazardous. it burst in my hand as i was carrying it to the table.granted the fact that it leaked most of the time i tried to brew tea in it.this product should be banned from sale. it's not safe. it's not functional. there's no option for zero stars, sorry i have to give it a star at all.

The product was defective or was poorly designed in general. The cup leaked every time when you put it upside down to brew a tea, I believe there was a sealing issue and in the end after a few weeks of use the glass part literally exploded !

Man, this cup comes with so many functions which would serve your drinking with tea or not in a perfect manner. I just love it. You can never go wrong with its quality.

not good. Will leak

I guess this is a bottle-like kettle

Leaks!! Not a complete waste of money because you can use the cup and the tea filter as two separate cups. However, if you use the filter with the cup as advertised you will have a leaky mess. The filter and glass are a nice feature used on their own and the cup has a silicone coating to keep knicks from ruining the appearance. However, you could by thermal cups at a fraction of the cost of these one.
