Review on YETI Rambler MagSlider Lid Replacement by Bill Pulakanam

I didn't actually purchase this item as a replacement cap. I bought a lid specifically for a magnetic slider for my Yeti 20oz coffee mug. Here's the story: I have a 20 ounce mug and just lost the magnetic slider. But to get another 20oz magnetic cap I would have to buy 2 caps for $20. But I could buy a spare 30oz cap for $9, remove the magnetic slider from the 30oz cap and use it on the 20oz cap. It worked great and I threw away the 30oz cap (no magnetic slider). But if you need a 30oz cap this was the Yeti cap (not fake) and it will fit your needs perfectly and I recommend it. But if you want a magnetic slider for a 20oz cap, that works and it's cheaper too. Hope that helps.
