Chillz 20 oz Stainless Steel Tumbler with Straw and Lid

Very happy with these cups. I have both the 10 and 20 ounce size. I originally bought the 10oz for "on the rocks" type drinks around the patio. It worked great, drinks stay cold and no sweating. Soon after, I noticed that the 20 oz was marked down to a ridiculously low price and I bought two instantly. Glad I did as the price rose back up the next day. Its still a good deal and currently cheaper than the 10oz. I'll use the larger ones for beer or milk shakes. Both 10oz and 20oz have always open lids as pictured. These are sippy cups and there is no closure. The 20 oz includes a straw but you could use your own (preferably shorter) straw for the 10oz. These probably would not be my first choice for a travel mug. They are great for around the house or yard. The lid is adequate to reduce the chance of leaves or bugs falling into you drink but could allow splashes in a bumpy car ride. The 10oz is straight walled and the 3.5" diameter might be awkward for smaller hands. Its very stable though, nearly impossible to knock it over. My wife has an Oggi Cheers wine cup and prefers the egg shape of that cup for her hands.I was a bit skeptical, the product box only describes these as double walled. It does not say vacuum insulated. There is a difference, but these have proven themselves to be well insulated. At room temp, these will still have some ice after sitting overnight.

This product is terrific. My daughter was skeptical & wanted a YETI, this is all that and more. I had a problem w/ the lid because the seal was crooked, they promptly sent a replacement & it worked great. Straw is a super nice bonus. Don't be hesitant, for the price, this is top notch.

Gotta say I have been impressed with the ability to keep ice for almost three days. This is a great cup. I haven't used the straw as much as I thought I would, but it is a nice extra. Easy to clean. Smooth stainless finish. Top fits solidly. Will probably get my wife one as well.

Love it. Keeps my bedside drinks cool and the metallic straw gives another chilling overlay to your already cool drinks. I think metallic straws should be the standard! Loved it so much that I bought another one for the office.

I don't like the fact that the lid doesn't fit tight. If it drops the lid comes off making a mess. Otherwise meh.

Using it at work now. Very good for keeping water and coffee warm. Haven't tried cold liquid yet.

Very good product. Looks good. Maintains the temperature. Worth it. Only negative - there is a hole at the top for the steel straw thru which dirt and other particles can enter

Just what I was looking for after breaking two similar cups. This thing won't break!
