This item is rather fragile and you have to take great care when handling, washing and using it, especially with the beaker which is made of thin glass. The metal housing is also thin but less of a concern since you can bend it back if it becomes deformed. Making coffee, you can't rush it, especially if you use a fine grind like I do (espresso). Would work better with medium or coarser grinds. However I like the coffee it produces better than my auto espresso maker or the traditional Italian stove top pot - the coffee comes out less bitter.
