The size is the same as the standard Doxy (so it will take the standard sized attachments). However, it is heavier at 830 grams (680 grams not including the plug). The head cover is smooth pure medical grade silicone. The body is made from a polished aluminium/titanium alloy. After casting, the body goes through a five stage polishing process that brings up the high lustre finish. The three large simple buttons are lit with blue LED lights so you can find them easily in the dark. The Die Cast has a variable escalating pulse setting (like the standard Doxy). It operates with any voltage so can be used safely anywhere in the world (with a suitable plug adaptor). The product comes packaged in a custom-made zipped padded case for easy storage.
