I have the Emsa EMSA CONTURA 504 180 now in use for a few weeks and have to say: It is the best Wanda dispenser I had been! Previously, I had Leifheit and casa (looked almost identical to each other out) and I both had the same problem during roll changes. Once they had taken off the panel and wanted it put back, it no longer held true, because the left and right two buttons were that needed to be pushed to lose weight, but do not get out oppressed the fortified again ... As soon as I moved to a film came to me the entire hood counter. This is at this Wanda dispenser Emsa fortunately not the case. Here there is only one head above the one pushing down and flips the visor down without completely remove. Then simply pressing it back up. A little caution, so you do not squeeze the finger, but otherwise top !!! So to be a Wanda dispenser, quick and easy in use and changing roles.
