If you want to buy a new inflatable jumper for daily use or rental business, of course you will consider the manufacturer. A bouncy castle rental company in operation is unlikely to resell their inflatable equipment, if they do, it means that this used inflatable is very likely not suitable for rental anymore. Although not all the second-hand purchases are a great deal, but you can get what you want with a small price, so most people are willing to take the risk.
