"This delivery company is the absolute worse. They shouldn't even be called a delivery company, but instead a never deliver your order company. They will lie right to your face telling you your package will arive tomorrow, then it never arrives. Then they make up all kinds of excuses and tell you for sure the next day. Then......nothing. I will never buy from any online store that uses this shipping company.....EVER! This means you MONOPRICE."

"This company is the worst overnight delivery company on earth. The companies I buy from and ship deliveries without signature requirements, yet GSO says the shipper has requested signatures. Checked with company and unless it's over $100 value no signature is ever required. GSO has failed to deliver without fail every time. They are unreliable to get deliveries on time. Count on fighting with them to get any results. They are terrible, no matter what their company slogan is, they are completely opposite, they never deliver on time ever."
