Previous models had too small a filter, so that when the desire for strong coffee filter is overcrowded and has clogged the device. This is now corrected. I use the device to morning 1-2 cups 'Mugs' coffee brew. I like the coffee strong, two teaspoons per 'Mug.' The filter holds without problems the ground coffee and the appliance runs without Pobleme and reliable. Any of ground coffee can be used, what is important for me because I like to try unterschidliche roasts, and fresh beans grinding (mill is not in the unit included). The device is fast, uncomplicated and easy to use, automatically turns off when a cup is gone. It can be brewed in quick succession and several cups. The coffee is vegleichbar with any good filter coffee.
With a professional coffee machine with pressure infuser can the Solac certainly not record, but all in all it's a decent device for daily use. The price-performance ratio is reasonable and I can recommend the Solac.
