I've been making cocktails at home for a while and this shaker has been a great addition. The triple-insulated stainless steel really keeps drinks cold without my hands getting numb, which was my main problem with my old shaker. The screw-on lid seals tightly and doubles as a measuring cup, and the built-in strainer means I can pour straight into a glass without reaching for a separate strainer. It's simple, sturdy, and does exactly what it promises.
