Ordered this to lay some vinyl tiles as I have medical issues with my hands which makes it difficult to hold standard scissors or a Stanley knife and it worked a treat, made laying them so much more easy. This is one gadget that I never new I needed but now wouldnt be without! It comes with 2 batteries, a charging dock and 2 heads, one with half a circle marking for thinner materials and one with a full circle marking for thicker materials I love the fact they are marked this way makes telling the difference between the 2 blades easy. I have cut vinyl tiles, carpet, cardboard and lots of paper and it cut every one of these with ease. Battery lasts around an hour of continual use but because this comes with 2 batteries this time was ample enough. This has to be one of my favourite buys this year so I would definitely recommend!
