Review on 🔫 LockNLube Pro Pistol-Grip Grease Gun by Michael Bressler

It looks like a quality grease gun, but after installing a cartridge of marine grease I tried lubricating the bearing partners on my boat trailer hubs (i.e. not It requires tremendous pressure to fill with grease.) Upon completion of a hub, about 8-10 pumps of the gun, grease began to spill from each lube system port on this gun. I dismantled all the hardware, wrapped it in tape and reassembled it. I made another hub and I still had grease leaking out of the 360 degree swivel fitting. There is no way to tighten it. Every time I use this gun I can expect grease to spill out of this fitting and make a mess. Pretty bad design, especially considering the price of this weapon.
