Taotronics products are generally well presented and good quality, this one is no exception to the rule. Although at first glance, the product is not as pretty as some other products, it compensates with robust finishing. Even finding that the previous comments, take the helping hand, I will say about 5s / page trying to be linear over the duration of the passage. The page is built quickly and the result is impressive. it takes 1Mb to 4Mb in 300dpi for the 900. Attention, it is important to have a microSD card, the cord is only used to transfer photos / pdf. Indeed this does not scan directly from Photoshop for example. but this lack is precisely compensated by that there are no driver during installation. It works directly. The images in jpg or pdf will subsequently reworked in Photoshop. It is important to note that the pictures are prettier than those taken by phone, after all it is also an alternative solution, but here the fact flatbed scanner allows for an image that is not oriented or deformed in the corners. Secondly, this unit operates on AA batteries, one could imagine a device with a battery with charging via USB. In short, a good product easy to use and saves space
