I really miss having a printer at home but I only need one ocassionally and the ink/toner is very expensive, plus its bulky to have using valuable desk space when rarely needed - this product has none of those drawbacks!When I took it out of the box, I charged it for a few hours, then read the decent manual which had me get a pretty decent UI app and within a minute or two I was printing! I increased the "depth" from default of 4 to 6 because prior experience w the thermal printers taught me to increase "depth" if you want the text to be as substantial as an inkjet printer.I can't notice any inferior qualities of the printed text compared to my regualr printer, even the graphic logo I printed looks correct! The only downside, if you're printing important documents, is that a) the pages come out curved because they're coming off a roll (but this is how its compact) and b) like any thermal printer like a reciept printer in a register you have to tear it off at the bottom and so the bottom is jagged. Small price to pay in my opinion because a great advantage is that you can print legal size paper or really (practically) unlimited length (regular 8.5" A4 US Letter width) pages!I used it on my iPhone via bluetooth but my iPhone also recognized it via wifi (and I believe it can connect via usb). This was one of the easiest devices I've ever used. I expected it to work like any AirPrint wireless printer in iOS - it doesn't, you have to share your document to their "Tiny Printer" app - but that worked just fine.
