Very easy to set up and use.
This gun is amazing.
Best grease gun I have ever used.Took all the work and mess out of greasing.
I really like this Professional Pistol-Grip Grease Gun. I used a lever type grease gun for many years. However, I had an injury to my upper right arm and lost several inches of bone which made it impossible to operate while holding the coupler on a zerk. I switched to pneumatick gun for several years, but I found that I had to disassemble and clean the the pump of hardened grease every time I used it. Finally, the trigger broke during my last lube and oil change. I then made the decision to get a new grease gun that I could use. When I found the Lock N Lube site and this grease gun including the locking coupler (with spare parts) I decided to get it, and the barrel cap. Since I had already done the oil change, I had to wait for a good time to lube in the event that I would have to jack the car up to do so. With this gun, I was able to lube the right side ball joint by turning the wheels to the left. Unfortunately, I could not reach the zerk on the left side by turning the wheels, so I had to jack the car up to get that done. At any rate, this gun makes the job easily doable at oil change time. And, of course, this gun makes lubricating other items easy. The barrel cap will keep the drips from the garage floor too. I think I'l likely gat a 90 degree coupler to go with it before the next lof job on the car. This is an excellent tool, and I can highly recommend it.
So far I am pretty happy with the grease gun. I have noticed coupler has to be "jiggled" around the zerk to make sure it attaches properly. I also ordered 10 tubes of Paragon 3000 Moly Grease with the grease gun. The tubes of grease were not shipped with their original package and 3 of the tubes were damaged. It is a little disappointing the tubes of grease were damaged do to lack of care when the package was put together for shipping.
