His product knowledge is awesome. When we ask Gus to sell, he really made a “research” , and came with many suggestion. Give us good insights – and he is VERY HELPFUL…. always answered our calls, GUS is a super polite person, when discussing things, he never lost temper. Always courteous, helpful and pleasant. I will ask Gus service again – when we have things to do in Melbourne. Thank you Gus.
