After almost 15 years of trouble-free use Aquabar was needed something new, which is visually not too ugly. Due to the enormous height of the CRYSTAL you can not use under wall cabinets. The opening of the device by turning (after bubbling) was sluggish because of varnish on the castings already gave up after a few weeks. This paint could have been even save but with intact paint is to use the first time, of course, more comfortable and gives little cause for conversion (a rogue who thinks evil of it). All in all, the handling is far more steps than connected with the old Aquabar UDN also the larger (and more expensive cylinder) hardly keep longer - perhaps because the bottles also have less volume.
