Great product

The tool is amazing, makes the job much faster. Shipping was slow to Alaska, would have payed extra for priority mail instead of sending it parcel post, and it taking 3 weeks.

M18 w/ Lock-N-Lube Coupler - Incredible Customer Service!

Best decision ever to buy this grease gun with the Lock-N-Lube coupler tip. Very easy to use and makes greasing my tractor much easier. I had one zerk on my front end bucket that would not flow and made the bonehead decision to lift the bucket to see if that would help. BIG MISTAKE, I pinched the Lock-N-Lube coupler and broke an internal fitting in the tip. I sent an email and asked if they had a bonehead warranty on the Lock-N-Lube grease gun coupler and within an hour I was sent an email back saying a replacement was on the way. THANK YOU Lock-N-Lube! I was really bummed after being so excited just moments earlier. Customer for life!
