great little gun, im impressed with the grease so far, only slight problem with the gun is over spill, just like a silicone gun except you cant release the pressure so grease still snakes out, its not bad at all though, well worth the money!
The grease gun is a good way of making sure the grease only goes where you want it. Note: When you first fit the gun onto the tube, I suggest putting a couple of turns of PTFE tape (like plumbers use on screw joints) around the tube's thread. This makes a nice tight joint. Then squeeze (not pump) the grease up into the gun and it will work fine.
Looks like main body is made of plastic, but it is in fact alu., so even better then expected. Works just like the Finish Line Grease Gun. So get this one instead! The grease is so far nice, but cant say weather it will last...
