Great product

I love these tumblers, I bought them for my grandson. I remember using them when my daughter was his age. Shipped very quickly and in great conditon.

Very Durable!

Pros:
Only 2 pieces
Easy to clean
Sturdy
Tight cover

Cons:
Leak when upside down

These cups are the way to go! They are durable and easy to clean. The covers do not get chewed up as easy as some of the other cups we have used in the past. I like how they only have 2 parts to them unlike many other cups. These will drip when tipped upside down. I find that with the "non-leaking" cups they eventually leak over time anyway. I would recommend the Tupperware cups to anyone!

Great for toddlers - Smoothies, Milk & more

Our 15 month old twins love to drink homemade smoothies from these cups (that's how I sneak veggies into my little fruit lovers - adding frozen spinach, kelp, and almonds or almond butter into their banana, blueberry & almond milk smoothies). They are great for trips too, and visits to friends houses when bottles and sippy cups aren't always at hand.

Cups are great, but the lids are terrible

I ordered these cups because I needed to transition my toddler from sippy cups with handles to a regular cup that he could grasp. I liked that it came with a lid for liquids I didn't want to risk spilling. Unfortunately, while the cups are great, the lids are flimsy. They are difficult to snap on, and after three weeks of use, my toddler has already chewed the spouts to the point that liquid will barely pass through.

Good cup -- but don't count on the sipper seal. They are not of the same quality as the cup.

great transition cup

I bought these tumblers with sipper seals as a transition from typical "sippy cups" and was not disappointed. They are a great size/portion for my children at meal times... and are frequently used without the covers as well, by my school aged children. My toddler loves her new cups! As a side note, I was looking for the tumblers with sippy covers because my grandmother had a 15+ year old one in her cupboard and I was trying to find the same product... the covers attach differently than they used to (were screw on, now press on) and I wish they hadn't changed (less possibility of opening by little hands!), but I am still very happy with them.
