I like it better than the slider lid cause easier to clean. But I tend to use it with my 18 oz travel mug for hot tea, which causes it to crack in time. But not bad crack cause it doesn’t leak.

Love it, better than the one it comes with. Easy to drink from and clean! Only problem is that it eventually cracks, don’t know if it’s caused by drinking hot drink. But love it anyway.

My big Swig has been tipped over, knocked off tables and counters, and dropped several times in the last almost 5 years. This last time killed my lid for good and left a huge crack and a large chip so the lid wouldn't stay on and I finally had to replace it. Hopefully this one will last me at least another 5 years!

Love the EZ flow feature!

Perfect!!
