item preforms as advertised. unhappy with the monogram. You can hardly see it. Wish the color was as dark as the MiiR logo.

Replacement lids worked better than original

Both replacement lids work well and are better than some of the lids that came with 2 tumblers I recently purchased separately from each other. One of those original lids that came with a tumbler didn‘t seal as tightly to the tumbler (the seal was measurably different) plus the sliding opening didn’t stay in the closed position very well resulting in some of the coffee spilling out when walking around. These replacement lids fixed those initial issues.

lid leaks all over me when I sip

The lid looks great and seems it should work well. However when I sip my drink, somehow the liquid will spill and leak out, dribbling all over me making a mess. I've fit the silicone gasket properly, and even tried the other way. Also I tried sipping differently to see if I could prevent the leak. Overall it seems bizarre the lid would function so poorly. Sadly I don't want to use this rad mug.

Poor Slider

So surprised to be disappointed with a MiiR product. We love our camp cups and water bottles. The slider feels cheap and rattles in either position.



If your slider is moving around freely, contact us at and we can get you set up with a replacement lid.

Press fit slide lid

I think it’s a good lid with some room for improvement! The seal is very difficult to stay in place, with all the ridges etc. it comes off its track every Tim you close or open and it ends up stretching it and also difficult to clean! Perhaps a solid ring would work better?
