Question: Does the lid screw on?
Document: Another $25.00ish dollars down the toilet. I am not sure if I will return these cups only because I know they will screw me outta my refund then resell this crap! Run,,,do not walk away from this product and this company!
There isn't a slider to go over the hole in the lid, so they will leak. Otherwise, the style would be perfect.
LOVE the mug BUT the drinking hole on the lid does not have a slide cover so the HOT coffee just spills out!!!!!!!!!!! and gets cold
Great two pack... not the prettiest products, and fit a LOT of coffee. But the lid fits securely and no risk of spilling.
good cups with a secure lid but not well insulated. can feel the heat on outside after filling with hot coffee. drink does not stay warm long in a cold enviroment
There is no way to close the hole so the beverage will spill out if tipped over. I took the lid off my cracked cup and put on the new cup, but I do notice that the lid does leak now, but doesn't leak on my old mug. Very disappointed.
The size is larger than I expected. Will not fit in my cup holders. The sipping hole in the lid does not have a closing tap  and stays open to the elements all the time. Might work for an office or in home but not for dusty conditions.
I was (at first) thrilled with this set of awesome jumbo coffee mugs as my previous ones were over a decade old and the lids were falling apart.The black one now leaks from below the sipper lid... onto my shirt.
One of the mugs had a defect inside so I couldn't use it, the black one gets used every day. What I liked about these mugs is the lid as I can put them on my night stand and not spill too much if I accidently knock it over.
I used an Aladdin mug for my perpetual mug of ice water for years until it jumped off the roof of my car. This ThermoServ mug is virtually identical. Has a hole in the lid large enough for my straw. I was very happy to find this online and am very pleased with it.
