Waatfeet Manual Frozen Meat Slicer

This meat slicer does what it does however it is difficult to use if the frozen meat is not in a perfect square-round shape to fit the slot to slice. It wont slice evenly if the shape isn't correct/perfect which makes it difficult to slice. The sturdiness is also not great. There are rubber foot to keep the slicer in place but it still moves around. It does work in a pinch for korean bbq and shabu shabu but it really leaves me wondering if i should get the electric one or not... My arm gets sore the next day every time i use this because i am using all my force in different positions to slice the meat perfectly. Once you get into the momentum of slicing your perfectly molded meat then it's not too bad.
