Tractor so much easier

This is awesome. Holds firm and prevents grease leaks when servicing.

this thing is great-like having three hands

In my eyes well worth the money. Gets a death grip on the fittings easy on and easy of and best of all no leaks I just wish I would have found it sooner. GREAT PRODUCT

Makes it easy to service my tractor and equipment

This is as advertised I have used this once since I purchased it and it does not leak grease at the fitting like a conventional grease gun fitting would I hope to use it many more times with less cleanup.

Works great, but I did find I couldn’t get it into tight spaces like the U-joints on my Chevy. Outside of that shortcoming, it makes greasing a lot easier.

I have a tractor that has multiple grease fittings that need to greased on a regular basis the Lock and Lube makes it easy to do.

I use this product to lube my truck and fifth wheel toy hauler and anything that needs grease.

Good product
