I got these glasses for several reasons. 1. I prefer glass over plastic for several personal reasons 2. They are a great size and easy to hold 3. Classier and unique way to serve any type of drink. They fulfil all of these requirements. However, I didn't think through the glass straw inside a glass cup. These are not good for older kids who proceeded to just jam the straw down through the suction hole section. Thankfully, they didn't break but the straw is pretty fragile so this is something to be aware of. The other drawback is the rubber suction plug in the bamboo lid is not permanently attached. 1 of the 4 plugs immediately pushed through into the glass when I inserted the straw - which I did gently. It feels like the hole in the lid was made just a little to large for the plug. I also recommend handwashing all parts due to the fragility of the set and to preserve the lids with the plugs. I did give it 4 stars for 'easy to clean' because I cannot just put them all in dishwasher which is the most convenient.
