Title: Excellent product for regular SUV service
Review: Trying to grease the drive line on my 4 wheel drive 4 Runner with a standard grease gun coupler was a PITA. This coupler is fantastic. Easy on, easy off and the grease goes where it’s supposed to. Money well spent.

Title: So effective and helpful!
Review: Absolutely love this grease gun attachment. Frees up one hand to pump grease. Too often, greasing requires one hand to keep pressure on the grease zerk so the grease gun’s hose and fitting don’t pop off. This eliminates that problem. Also, I owned a Cub Cadet lawn tractor that had all of its grease zerk fittings pressed in, rather than threaded. Removing the press on style grease gun coupler would often pull the zerk right out of the hole, requiring the zerk to be hammered back in. Again, this quick, clamp on coupler eliminated that problem. Seemed a bit spendy at first, but now I feel it’s worth every penny.

Title: Excellent product
Review: Why did I wait is my question. Works like magic, easy on and off the fittings, doesn’t leak or come off until you decide to take it off. Buy one, they’re awesome.

Title: Great Customer Service!
Review: I ordered the Lock N Lube, but it was WAY past the 30 day return period before I had a chance to install and try it out. It works great, but due to arthritis in my hands, I had a very difficult time squeezing the spring loaded lever to open the jaws. I messaged the seller and explained my situation. I received a very fast response from Carleen in Customer Service, who instructed me to simply mail the item back for a full refund!!I’m very satisfied with this transaction!!

Title: Bulky but high quality
Review: This will not fit in tight places. It’s bulkier than I thought it would be. The button release is giant. But it works awesome and comes with a rebuild kit. Not a common practice at all. I like it.

Title: LockNLube Grease Gun Coupler Works GREAT!
Review: I have a utility Tractor that has 36 zerk fittings that need to be greased every 10 hours. Also have a Milwaukee M18 Cordless 2-Speed (electric) Grease Gun, which makes greasing much easier, although grease leakage at the coupler can be huge. So I purchased a spring loaded Grease Gun Coupler for about $14. Although it worked better than the standard grease gun coupler, it still leaked a lot and made a BIG mess! Finally, I bought a LockNLube Grease Gun Coupler. It works great. Almost no leakage. Even though it cost 3x my "1st" spring loaded coupler, IT HAS BEEN WELL WORTH IT.

Title: Best of its kind
Review: The Good:Very well-made and even comes with a spare parts kit. Locks on zerk fitting securely and releases easily when done. No grease blow-by. I now use them on all my grease guns. Because it locks but releases, no more wrestling match to remove from fittings, and no more torn out zerks (yes, it can happen.) There are many similar devices on the market; this company makes the best.Room For Improvement:Wider than a conventional grease gun tip, so it sometimes won't fit into narrow spaces. Also, on the expensive side.

Review: Absolutely worth the money. Locks on to the zerk fittings beautifuly, no leaks, no more need for 3 hands to grease equipment. Even forces grease into stubborn semi blocked fittings. Paired with my new milwakee m18 grease gun make an unbeatable team.Would recomend 1000%

Review: This clamps on securely and lets me pump grease into fittings that the old adapter would let just leak out around the sides. Tricky to fit into tight spaces, but what can you do.
