I have been a customer of Marco for the past two/three years and every time I need something he deals with, he is my first and only stop.
I appreciate that he is not pushy at all, he takes the time to understand one's needs and to find the best solution for such needs. He also explains the reasons for his suggestions in detail, offers you various solutions, but in the end, will sell you whatever you think it's best for you with a friendly smile and supporting your choice and with sound advice.
He has always had an explanation and answer for the product-related doubts and problems I have had and I really think it's hard to ask for more than he provides when it comes to customer service.
He offers thought-out advice and if you talk with him, is pretty clear he knows what he is talking about, which is something not that common to find.
Tl.dr.: all the appreciation this shop receives is well deserved. Amazing customer service and know-how!
