Only small issue is that the rubber gaskets come loose. Works very well and doesn't leak. Keeps drinks cold on standby. Never leaks. Never an issue after being in the dishwasher.

This is now on my go-to gifting list. I will now be referring all my friends and coworkers to, and i look forward to purchasing from them again.

Both pieces are threaded, and screw onto the shaker. Easy to unscrew. Standard coffee cup lid is the most insulated one i've ever seen. Double walled insulation keeps your mixes cool on the countertop.

This cocktail shaker looks and performs great! This thing is solid and durable. Also the color options make it an amazing conversation starter!
