The glasses are okay ,but I prefer glass not plastic.

I purchased the set from my local club and it holds very well in the dishwasher.

these are NOT dishwasher safe. Misshaped and warped on the top rack of my dishwasher :(

Really nice glasses, lite weight, cool design easy to hold due to ribs added on the glass that make really easy to hang on to and not slip off hand, makes great add on to my kitchen. Thank you for allowing me to test and review.

They're nice compared to glass tumblers as they are more durable and can withstand more wear. I bought these to use at home. I have two kids and wanted glasses for all of us that would stand up to being knocked over and thrown in the dishwasher and could also be used outdoors. 

Mine did very well in the dishwasher. And I love how they stack in the cupboard. Really happy with the set so far.

The rainbow pack came with two light blue cups in each size, and is missing the darkest red/plum color.

This tumbler is light weight but not flimsy so it seems durable. The ribs are decorative but help to keep a good hold on the cup. I very much like these cups and they come in 2 sizes, so there is a cup for every member of my family.

The colors are absolutely gorgeous! I like the ribbed texture because it not only gives it a pretty design, but made it easy to hold onto. It became my husbands favourite cup to drink out of. It's very well made and pretty sturdy.

These tumblers have survived multiple drops by my youngest. I regularly wash them in the dishwasher and still look as pretty as when I purchased them.
