I'm a cocktail bartender by trade but this one is for my home bar. I've had the 55cl shaker for a couple of years now and it's really something. It feels so solid in the hands and chills drinks like no other. It can sometimes be difficult to crack the seal on the lid and given the delicate nature of the silver plating you don't want to be rough with it but if you carefully wiggle the lid it will come off. Finally starting to see the inevitable copper showing through the plating after plenty of use but I don't think I'm at the point of needing it relined yet. Very durable and satisfying product. I'd love to try the Izmit shaker someday since I use a two tin system at work. I'm curious how good the seal is and how quickly the silver plating will wear at the points of contact. Maybe that's why they offer the Izmit in solid silver? Wonder how much that will cost you.
I own 2 Soy shakers (one 33cl and one 55) that were gifted to me last year, as I am a home bartender and a mixology nut. You can't even understand the difference until you start using it, as it is tremendous! I do not ever need to do a dry-shake since I am using Soy, and for the ones who know about bartending, that means a lot of time saved! I'm eyeing all the other Soy bar products now!
