Stainless Steel Cups (4 pack) by MrLifeHack - Healthiest & Safest Drinking Glasses - Great for Kids, Toddlers, Sippy & Outdoors -Premium Unbreakable Metal Tumblers - Available in 3 Sizes (8 oz)

Got these to replace plastic ones (not liking the plastic, even though they're the cute Ikea colorful ones). Went with 8 oz size. Got silicone 'sippy' lid covers to help with spills (older but distracted and clumsy child), and couldn't be happier. Have only used them with cold drinks so far, as he has his hot choc in an insulated tumbler of mine. So far, he's happy with them and likes the bigger boy feel and size of them, is amused by the condensation (yes, they will sweat with ice in them), and hasn't spilled anything with the covers. They pop in the dishwasher and are easy enough to hand wash as well. Will update if anything goes amiss, but they seem good, sturdy, and functional, and I love that I can add the (separate purchase) silicone covers to top and no spills, and we can get rid of those but keep the cups when they're no longer needed.

These are nice cups and what you see in the advertisement is what you are getting vary the size. They are stackable and are not hard to get out when stacked. I would be careful if you place something hot or really cold (a lot of ice) inside of it and them attempt to drink lol. You may want to purchase a sleeve for it.My grandmother would give us these cups to drink out of when I was a child.

I was happy to find these and really love everything about them so far. We've only just started using them today, but so far so great. You do need to take the step they tell you to in the package insert which is to pinch the openings so they work properly, but that is no big deal. They look great and I have a feeling they will last.

These have been the best purchase so far for my toddler. Easy to clean and store! The mrlifehack sippy cup lids that are recommended with the stainless cups are also extremely sturdy and simple to clean:)One of the cups in the pack had rust in the bottom, (just a packaged defect), but I contacted the supplier and they responded quickly and sent a replacement!!Thanks for an awesome products and awesome customer service MrLifeHack :)

Good sturdy product, however this product was sold by a marketing group not a supplier. You will not be available to find this size product on the internet.

I purchased these cups for my grandson to go with the sippy cup lids. They are durable, easy to clean and we don't have to worry about any harmful chemicals that are sometimes found in plastic. I highly recommend the lids. They have been a life saver for my grandson and daughter. He's able to get the nutrition he needs in a timely manner, thus he sleeps and my daughter gets some rest.

Got these cups for my 4 year old son. We don’t use plastic and I needed something that he could use without being afraid of him braking glass. These are really nice and don’t take up a whole lot of space as the stack really tight. I will be getting a few more. They keep you drinks cool for a good amount of time.

I bought this cups for my 5 month old baby, I think stainless steal it’s easier to disinfect and better for my baby. I order the sippy cups lids also, and cannt wait to use them.
