Certainly, and no offence meant.
The thing with trade shows is they are surprisingly expensive (costs include travel, accommodation, space rental, stand design & build, power, flyers, freebies, and much more I've forgotten), for little or no immediate gain.
Very few sales are made at trade shows - it's all about brand awareness and making sure people know what you do when they next need something you sell.
If a company exhibits at too many shows in the same region in a year, the costs soon outweigh any positives that being at the shows would bring in the longer term, so it's all about striking a balance.
Shows in Europe will be expensive for Ross-Tech as they have to haul everyone over the Atlantic, so the balance would tip very quickly if they attended more than one show a year in a European country (or even in Europe as a whole!)
Your profile says you're in Poland - your best opportunity would probably be Automechanika in Frankfurt, which happens every other September - the next one is in 2020.
