We have these stocked everywhere - the kitchen, office, truck, and camper. We have now begun buying these as gifts because everyone sees us with our emotional support tumblers 24/7 and loves them. Great quality, however we far prefer the "old" style of lids without this sliding component. I actually requested to have these sent to us because the "new" style of lids are already collecting grime, are extremely difficult to clean, and we keep spilling on ourselves with the flood-out design.

I ordered multiple colors of this tumbler for my friends attending a bachelorette party. They are very sturdy and held up well in the dishwasher. The lid scratches easily (be careful with any abrasive sponges!) and not all models/colors seem to have the closable lid. The one I ended up with had the non-closing lid, but it still works well nonetheless.

This tumbler is perfect. Exactly the size I love and the lid feels really pleasant to drink from, unlike many travel lids!
