My new stand arrived about a week later and true to form is almost completely industrial grade steel and very heavy at about 20 pounds (about 9 kg). Gostei muito da rapidez na entrega, foi presente de aniversário do meu filho,e ele amou, chegou até antes do dia do aniversário, e eu estava tensa com medo de não chegar. I definitely wont run out any time soon! I need to test it. 28/06/2020 still staying strong. I think they are great for everyday use for 6 months but I wouldnt expect to get a year out of them. 50% Akku in der Box. Die Verbindung schnell und Klangqualität ist wirklich super. That?s the issue I have. I live in a small studio apartment and can?t have bulky things so these work great.
