I still want the real deal, but this one works for now, takes a little practice and adjusting, piston seems to be tight at first, but once it breaks in, it runs smoothly, prior to inserting meat rub it with some oil or butter and work the piston up and down. Air inside makes it tight, so go easy, it worries me that if something breaks won't be able to fix it, don't know if spare parts are available, something to consider. If seller reads this, please clarify if parts are available for purchase if something breaks. Other than that work fine, makes 7oz patties and cleans easily.
