Battery life is excellent! After having purchased many sets throughout November & December to hold up different holiday ornaments and then finding that the others - although advertising as being ? Great for Walls? and in one case ?Great for ceilings?, none of others can be used on painted walls. After a few more workouts, I?ve snugged up the laces a bit and I?m loving the fit. Recieved on time and packaged nicely, with a part missing. Drove back to the staples. Decir "ok google, apaga la musica", y el dispositivo para la muscia y se apaga diciendo "Adios", ¿Considera que escuchar musica es tan importante que no se puede apagar? También me ha pasado no poder parar la música con botones, y tener que simplemente bajar el volumen al mínimo: menos mal que al menos el dial del volumen es decente. Hard and difficult to walk in at first buh gets better as u wear it more. Second issue is I find the material not long enough for my size of breast (36DDD) so the waist is higher up then it should be. This is awesome. Also, I do not understand the reasons for the few negative reviews.
