In some parts of the world they make a very nicely layered Irish Coffee: Simple Syrup on the bottom, a layer of whiskey, a coffee layer, and heavy cream on top. Impressive to see and tasty to drink. But IrishCoffee's not the stated purpose for this toy so I feel a little guilt giving it four stars. Adjust accordingly.Until now I've struggled just to make the common version of Irish Coffee in which whiskey, syrup and coffee are mixed together to make one layer, and the cream forms a second. Just making the cream float (whipped cream is cheating and doesn't taste the same) requires great care, so I had high hopes this gadget would make two layers trivial and four layers do-able.Alas, it didn't even work for the simple two-layer version. The cream really needs to flow onto the liquid from something like a spoon sitting bowl-up in the coffee, but with the tool sitting on the rim of the glass it dripped through the holes with enough force to mix.No applause from the audience, but we did enjoy drinking the failures.Might work fine for beers, of course.

the best way is when the bottom have a layer of foam before put the second layer

Got this set of cups for my husband as a gift. They are as described. I like this brand and the price was right. They keep drinks cold and the lids fit nice. The only reason I gave 4 starts is because of the wood grain print is uneven on one of our cups. We will keep them and happily use them, but to others this might matter more. Could say something about there quality control too.

We received these as a gift and have purchased 4 more sets as gifts.They are wonderful IPA glasses. Just don't put them in the dishwasher.

Very comfortable to hold, looks attractive. Priced better than others I looked at. Good buy.

While I love the shape of these glasses, the depiction of IPA drinkers sitting around, eating a tiny pizza is kinda comical. I make homemade pizzas. They are tasty. I enjoy them with my family. NEVER have I sat around and enjoyed a tiny assed pizza with my buddies. Why do I find this funny? Hell if I know...Cheers!
