So far there's no issues; quality steel, colour coating, lightweight without feeling flimsy or fragile, if I dropped it it would likely survive a few falls before getting damaged. Great for the price, I recommend this brand!These cups are very nice for using around the house or camping. The only thing I would say that’s negative about them is the fact that if you have a cold drink with ice in them, the outside of the cup will become a block of ice rather quickly. Makes it a little difficult to hold it and drink out of it once the entire outside of the cup becomes frozen over. Price you pay for metal cups that aren’t insulated in any way, I suppose.Happy customerSo easy to take care of, not breakable, and so pretty.Our kids have been using the 8 oz version since they left sippy cups behind. The adult sized cups are great too. It's the perfect sized tumbler for everyday use. I love how the cup stays cool in hand with an ice filled drink inside. I have pared down my cupboards to the essentials and was able to add a set of four of these stainless steel cups in place of a variety of cups and mugs. Knowing they won't break like glass or leach chemicals like plastics makes me happy.Well, these were well packaged and look solid, however, it took me 4 hours to separate them since they are stacked, or should I say stuck together. I put them in the freezer for about an hour and I was able to loosen the bottom one, then back in the freezer for another hour and it still was a struggle to loosen them. Finally after 4 hours I was able to separate all of them. Not easy, just pray they don’t rust.These cups were reasonably priced and totally solid. I ordered a few back in the Spring and they help up very well in daily use.They are durable, a good stand size, and clean up very well.I ended up ordering 40 of them. This should last me FOR-EV-ER.Omg! These cups are totally leak proof! They hold liquid just as a cup should! I would bet good money that the would hold anything without leaking. Dirt, legos, lubes or whatever. They are super easy to hold to. All you do is put your fingers around it and gently squeeze it. All the other cups I ever used either leaked, fell out of my hand or was super cold to the touch. These cups were made by Gods.As advertised just make sure you know what 16oz is
