I use the Brother P-Touch for several years and am very happy with it. With me are 6 Duracell Micro batteries in it, and last forever. I've never used a power supply. The operation is very clearly despite or perhaps because of the many keys, because you do not have wade through menus. It has a block of letters AZ, spacebar number block of 1 0, comma and period, function or menu button, cursor on the right links, key for upper and lower case. The display is a little small and only einzeilg what is somewhat impractical, especially in a two-line expression, but for the price this is quite ok. The cutter works to this day perfectly. The replacement of the tape is quick and simple, as are the batteries. Through a small window in the bottom, you can also see which band is immediately inserted. The whole unit is compact and fits comfortably in your hand.
