This DOES NOT fit Yeti 30 oz without following instructions, which doesn't exist. I would give 5 stars had instructions been given. I went on YouTube to find instructions and found one video with a guy heating the top ring with a special hot air gun (hair dryer on steroids). I don't own one of those guns, but the concept of heating the top ring was gleaned from the video. Here is how I made this work:1. Boil 3 or more cups of water.2. Find container you can put the handle upside down so the large ring is on the bottom and relatively flat. I used a bowl with flat bottom.3. Poor boiling water into the bowl until the large ring (not both rings) is covered in boiling water.4. While waiting for 5 minutes, put soap on the tumbler, the large top section (dish soap worked for me).5. After 5 minutes, put the tumbler upside down on a firm table or countertop, push the GetiGrip as far as you can.6. I used a small hammer to tap the grip further down until the small ring hugged the lip at the bottom of the tumbler. I scratched my tumbler on this step, so be careful or use tape to prevent this.

Meh! It's okay, but it doesn't stay in place and like others complaining about various products being too tight, this one seems designed to be loose and drop each time you set it down. If the top ring had the same lining as the bottom, it might stay up, but such is not the case. I guess I'll keep it, but if I had to do it again, I wouldn't. The carabiner is wasted since I feel certain the cup would be lost rather quickly left to dangle unsecured in this handle.PS-Update 1/16/17I discovered that by slipping one of the old neoprene / silicone coffee sleeves onto the bottom of the cup and pulling it up to the bottom ring, it is enough to hold it pretty firmly in place up and down, but it will spin side to side with the weight off of it. That makes it quite versatile since you can now spin it around to drink with either hand and the whole thing still comes apart pretty easily for cleaning. If the company would throw in one of those sleeves with the purchase, my rating goes to five stars. Since I had to come up with the idea and provide my own sleeve....

I needed a handle for my tumbler and the one that I ordered previous to this one was too big (even though I checked that I was ordering the correct size). The top rim was too big and whenever I set my cup down, the handle would slide down - it wasn't very snug. Then I found this set. What I liked most about it and made me order it was the little rubber strap. The handle that came in the set had the same issue as the first handle I ordered (the reason why I get it 4 stars), but the little strap helped keep the handle in place. It's always hard to guarantee fit on products, but at least this company has a solution.

Good fit and functional but would be better with rechargeable battery and charging port.

Glad to have this handle for my large cup. Didn't realize it would cover the inscription on the gift I was given.

There was a noticeable gap of about 1/8th inch between the bottom ring and the Yeti 30oz Tumbler, so the fit is not "Perfect Fit" but I soaked the upper ring in boiling hot water for about five minutes, and it expanded a bit more to allow the bottom ring to settle into place firmly. I do not need the GripBand. The construction is sound and sturdy. Not uncomfortable, but I wish the handle was a bit wider. Could use a slightly larger carabiner clip.

The bottom ring only touches at the handle. The top ring is not big enough to go high enough for the bottom ring to make contact all the way around my 30 ounce Yeti

My handle was just delivered a couple hours ago. I've got a Mammoth Rover 30oz cup, and much like the owner of the Ozark cup said, it works but it really doesn't fit. If you look at the picture, it looks like the handle goes up to about an inch or so from the top. On my Rover, it's more like almost 3 inches from the top. This effects the ergonomic feel, as it makes the cup top heavy. It feels like it's putting more stress than necessary on my wrist. The bottom band doesn't fit at all, it's loose. Seriously considering returning it.
