I have this Lumax LX-1152 and like it just fine. After having oil seep from it and making a mess storing between maintenance times on my truck, I have decided to remove the grease cartridge from it whenever it is not in use. That way the grease is not under pressure. I bought a plastic bin with lid at Walmart and just keep the cartridges and the grease gun in that.
