My landscaping company recently partnered with GST. So far, the best seller has been the W-Blade series. It seems customers want a middle ground between price and quality. Although the S blade is high quality, and sells well, it seems most "enthusiasts" I've encountered love the W blade series. I'm currently in the process of requesting more samples of pet turf and the super natural series as I've heard good things about them. The only complaint I have is that they have too many SKUs for me to keep up! It'll take me some time to figure out which ones are right for my company and customers. However, I definitely understand it now when people say that GST has everything you could ask for as a supplier.
