Good product
Its mini size makes it a great battery operated tool, no waiting for power on or off so very handy to move around quickly. Used mainly on battery and with USB key (it reads PDF, DOC, PPT, JPG and surely other formats), so no cable needed, it's perfect!
The only downside, but it's normal, is that it's a 900 lumens so it's a bit short when there's a bit too much sun! but in the dark it's great.
