“Fantastic product. I've been using it on e-textiles workshops because it is very easy to sew, it secures the battery well, but it is not too difficult to take it out (while building the project), and the on/off switch is a plus, since it allows for less complex projects for beginners (it eliminates the need to sew a separate switch component). Also, the extra positive and negative pads can be sewed as well for extra stability.”
