Great when they work unfortunately that's not for long
Great when they work. Unfortunately they are made with super cheap batteries I've now had two units that have broken just after the 1 year warranty. I wouldnt buy this product again. The paper is also really overpriced. EDIT: So people are aware the repair service requires you to cover return postage for the unit to China. Having had 2 units break in a short space of time, I can confidently say that sub optimal batteries are used in the machines.
