I was swayed into a purchase by all the positive reviews. My wife is a Yeti fanatic, I on the other hand just feel they are WAY over-priced. She has something like 8 different sizes and colors, and I always try to find something close. Well in this situation, I think this Sunwill 20oz tumbler fits my goals and expectations!I have been using my kids Yeti tumblers for the past several days for morning coffee, and decided to take a chance on this tumbler. I received it today, and immediately had to do the whole how is this compared to a Yeti?Do Yeti lids fit? CheckIs the size identical to the Yeti tumbler? CheckDoes the weight and feel compare? CheckHow is the lid compared to the Yeti? Meh, a typical cheaper lid that isn't magneticThis is my only negative with the Sunwill. The lid is a pretty typical run of the mill lid, you have to slide it to close it, and it has silicon seals. These are a bit tough to clean, and aren't as easy to move back and forth as Yeti. Also, the seals around the mount point are very tight and deform easily as you pull off the lid. The lids are indeed able to be cleaned, just close the lid's slide, then use a butter knife to pry the slide off its track. It will pop off and you can clear everything.Since I can get other lids or use Yeti lids, I don't consider this to be worth taking off points. However as a review for others, keep in mind that the tumbler matches our Yeti tumblers exactly by dimension, height, opening and base. It is only the lid that will likely need to be replaced in the future or will take some extra work to really clean out any coffee or drink residue over time.The other minor thing is that the directions are pretty negative about using a dishwasher. Yeti tumblers have no such issue, but these state that the insulation could wear off over time. It isn't a big deal to wash these by hand though, considering this was easily 1/3 the cost of a Yeti.
