Review on Filter under the sink Geyser Allegro M with tank by Jnis Zels ᠌

Very poor attitude to equipment and service. I ordered a filter with an expansion tank of 12 liters, in fact they bring it to 7.6. I contacted support at 18:00, in return they promised to issue a promotional code for 1000, I agreed. At 21:20 there is no promo code, which indicates a negligent attitude towards customers of the support service. Photo of the expansion tank compared to a 4.5 liter humidifier. I'm going to return tomorrow.
