I applied 2 times to fill a 10L cylinder with carbon dioxide and 2 times they have some problems, then the tank does not work, then the plant is under repair. Moreover, they say on the phone that everything is OK, come on. Why are you wasting my time? In general, my experience with Ariotech is like this.
Good reception, visitors, it's hard to work, the devil is the staff, thank you very much for your work, the factories and the population are very well such people, with more care.
