As a skilled do-it-yourselfer, I was dismayed to discover that Gruper's web store made some misleading claims. They state they only carry products from the best brands in the business, but my most recent purchase proves otherwise. I bought an instrument from them, and it was broken from the start. I tried to get a refund or an exchange, but customer support was unhelpful and wouldn't budge. It's obvious that they prioritize profits over client satisfaction when it comes to their products. If you're a do-it-yourselfer like me, I highly recommend you stay away from Gruper and look elsewhere for your building supplies.
